need some info before upgrading!

i'm using rebug 3.55.2 update 7 (or so i remember!), with reactpsn 2.2, ftp manager, multiman (so all the programs i use are already ported), and a lot of dlcs installed, oh, and i don't have any kind of hardware to flash/do things, now onto questions:
if i install 4.xx, do i lose all the dlc's i've bought/downloaded from psn and/or the ones activated via reactpsn ?
game signed for 3.55 works on 4.xx without patches or just by reverting to their original eboots, right ?

if the first two answers are no and yes, then:
which cfw do you think is better ?
i was thinking of installing rebug 4.21, but i can't just understand if it's doing the same things (+more) as their old 3.55.2 or not (it isn't talking about "automatic" reactpsn without selfs and suchs the 3.55.2 has)

thanks for the help

Also make sure to read about QA flaging. Since that will give you the will to downgrade if you don't like the higher CFW.
