Honestly I like how every faction seems different in Fantasy they all have their unique styles. If I had to choose I would say WHFB
For editions I honestly haven't thought that much into it Which would you guys recommend. for a beginner into WHFB?
For a beginner I would say
6th/7th, because most game concepts were less complicated and army design and playstyle was at its most thematic here.
6th is the most basic and probably the most new player-friendly, with probably the best level of balance. It was before my time as well but this was the Edition where GW really cared most about Fantasy, with them releasing loads of little mini-lists as well as the main army books, and pretty much every major faction getting a good quality book.
7th refined those main rules in some good ways and most of its army books are fine to use, but a certain three armies (Dark Elves, Daemons of Chaos and Vampire Counts) were made particularly overpowered and you'll either have to agree with any friends who play those armies on some limitations to their books (most notably disallowing the spell that allows the former two to generate additional power dice), or for those armies to use their 6th Edition books. But then as a beginner you likely won't be playing in a competitive environment so I'm sure any opponents you have will be reasonable enough to consider such amendments. The one good thing about GW not having jurisdiction over Fantasy anymore is that house rules added to improve balance can be more readily employed now, so might as well make use of that freedom and fix GW's games for them, as they've never bothered too much in doing so themselves.
Alternatively, using the 7th Edition rulebook and the 6th Edition army books is a way to essentially get the best of both worlds.
Then when you've got the hang of these editions, if you wish you can choose to gravitate to 8th where the rules were expanded and changed significantly (in some good ways and some bad ways) and most armies got a few extra units to play with. The balance lies someway between 6th and 7th, with some armies still being overpowered because GW loved them and some being particularly underpowered because GW hated them, but the level of OP-ness did not get as bad as the certain three armies in 7th Edition mentioned above. I would still recommend adding some house rules to improve balance as with 7th, mind, as the way they treated some armies was despicable in this edition and any players wanting to play these weaker forces deserve some extra help.
The choice is yours anyhow. Best of luck in your Fantasy journey!
