unlocking/flashing is not difficult. If you can follow simple instructions, you can do it. Differences between roms are noted in their release notes, the easiest way to determine those differences would be to read the release notes. the screenshots you posted are of winmo 6.5. IMO 6.1 is more stable at this point, and i despise the honeycomb interface of 6.5, however, to each his own. best suggestion i can make would be that you try several roms and see what you like. It does not take long to flash a rom, id say about 5 minutes max to flash the rom, and another 5 minutes to perform the first time boot procedure, reset, and be ready to roll. Read the stickies on unlocking your phone, then read the chefs comments on the individual roms to determine which one you want, then just follow installation instructions and enjoy.

ps. My personal favorite is mightyrom 4.
