When installing minimals you have MKII, XeTeX and MKIV. I understand that
you should normally use MKIV, but when are the other two used?

MKII can be used either with pdftex or xetex (as you wish, compare
advantages/disadvantages). MKIV can only be used with luatex.
You have to differ between ConTeXt »versions« (mkii, mkiv) and TeX backends
(pdftex, xetex, luatex).

And where do I find the advantages/disadvantages? Or can I just always use
MKIV?

Wikipedia, google, information source of your slightest distrust.
Short and incomplete:
pdftex:
+ protrusion, font expansion
- fonts are a nightmare
xetex:
+ system fonts are easily accessible
- no protrusion, no font expansion
luatex:
+ protrusion, font expansion, easy access of system fonts, scripting language
included, fast with mplib
- in general much slower
> Or can I just always use MKIV?
Yes, you can.

As already mentioned speed depends on the kind of document. In general
context runs slower with xetex and luatex if only because these are
unicode engines while pdftex is 8 bit.
Occasionally i do speed tests and it also depends on the operating
system, file caching etc. For luatex the size of the cpu cache also
matters. Although pdftex/mkiv is always faster unless on eused metapoist
in which case mkiv is a clear winner (the metafun manual runs in tens of
seconds in mkiv but takes many minutes in mkii. Comparing xetex/mkii
and luatex/mkiv is difficult as xetex also pipes its output to a dvi
backend. On some tests mkiv is faster, on some others mkii but I must
admit that i only tested simple document.
On a raw simple document, pdftex can be twice as fast as xetex or
luatex. The more lua driven features are used, the slower mkiv becomes
but in general it does a better job then.
Anyhow .. only luatex/mkiv will evolve so best stick to that.

They are mostly relicts of the past which still happen to be
supported. (But if ConTeXt was written from scratch, there would
probably be no support for them.)
I often write mathematical-oriented papers that need zero tweaking
with OpenType fonts, complex layouts or that could benefit from lua
scripting. I compile those randomly with MKII and MKIV, if nothing
else to check for differences, or if there is a problem in MKIV, I can
always use MKII is a fallback. MKII hardly ever changes, so it is
slightly more reliable in some cases, but it is very limited in
comparison to MKIV.
I use XeTeX mostly when I need OpenType fonts and something in MKIV
breaks. XeTeX has some advantages in out-of-the-box support for exotic
scripts (which I don't use), but many of its features are not
supported in ConTeXt at the high-level user interface. In general,
XeTeX is the least supported engine in ConTeXt community. In contrary,
for LaTeX users XeTeX is becoming the mainstream engine to use (best
supported by active developers).

I never tried to use them, but I thought that Han The Thanh [please
add the accents] added that to XeTeX semi-recently
(http://scripts.sil.org/svn-view/xetex/TRUNK/, the last comment 8
months ago: "merged microtype branch to trunk").

... depending on whether "in general" includes metapost or not. A
speed factor of ten (faster) is nothing unusual for luatex when many
metapost graphics come into play.
++ better support

Definitely. You don't need to bother, just stick to MKIV as long as it
works fine for you.

I don't follow xetex development any more, so my information was outdated.
Thanks for the correction.

I totally agree. But Cecil mentioned in another thread: »My document is mostly
text.« Even if a few mp graphics are involved luatex is still noticeably
slower.

I look at it from the perspective that the last time I used TeX, my 8MHz Atari ST took several seconds to process each page. And then it took several seconds per page for the previewer to show me the DVI. And I couldn't do anything else on the machine while it was working.
My way of working now is that I keep a short scratchpad document in TeXworks, and use it to sort out my formatting and macros, taking advantage of the live preview. When I'm done, I copy the definitions into my actual working document, which I edit in vim. I only typeset the entire working document once or twice an hour, if that; vim catches syntax errors. So if LuaTex takes a few seconds longer to do the typesetting, it's completely unimportant.

it's no problem to get a 250 pages per second throughput in mkiv but as
soon as you add more interesting things to a page work needs to be done
and that takes runtime
on the average i get some 10-15 pages per second for documents of normal
complexity on my (by now) 5 year old laptop that i use for development
which is quite ok (mk.pdf: 10 pps, hybrid.pdf: 11 pps, cld-mkiv: 15 pps)
