Well for the last year I've stuck solidly with dGB - yes, it really is a year!
OK, I've once or twice flashed Redux 2 (late 2011), spent a few days with MildWild Oxygen, and very briefly experimented with Sandvold's ICS, but I doubt that adds to a fortnight in total.
To be fair, the MildWild ROM was good (can't remember which version I last used), and I do have a soft spot for Redux 2 with its fancy notification power control. Both solid ROMs. Didn't use ICS long enough to give a thorough review - it was a bit less responsive, and I decided I couldn't be bothered with the effort it would take to set all my stuff up on it.
Prior to that in 2011 I'd used GingerVillain, various CM7s, Miui XJ, with shorter spells on Oxygen & Redux. My trend was towards lighter and lighter stuff, and I usually edited the ROMs before flashing to make them smaller (apart from Miui, which I didn't edit very much as I was less familiar with what was in it). All of these worked fine, Redux was the smallest and fastest of these, Oxygen also very good. Miui is different, and was a bit slower than the others. I found CM7 fine, but it requires more setting up (google apps and a2sd are both add-ons), and also I had usually removed 1/3 of the ROM before flashing so haven't so much experience of the full fat version. Have never run CM7.2, as moved off it before that came out.
Since I use a 3rd party launcher, and usually did a bit of UOT theming, the first order look and feel of these ROMs was pretty similar to me - some differences in menus or icon themes, but nothing much (Miui menus were completely different, but even then I used my normal launcher). So responsiveness and stability were the main things I would comare.
