I played Space Wolves as a young fellow long ago, so when I got back into the hobby with Kill Team I knew I wanted to play them again for maximum nostalgia. But Kill Team didn't *have* Space Wolf rules so I just ran them as the best melee team I could find - Deathwatch. Even when Space Wolf rules were printed in Elites it made sense to take advantage of the roster system to use more than one chapter, including having the same model occupying multiple slots on the roster to be different chapters for different games. So the base that I'm expanding from has been consistent in its aesthetic but all over the place in rules
The current context of 40K is that Codex compliant chapters are awesome - combat doctrines are fun, there's incredible depth of viable units, and if you want to run successors you can still access most of the goodies of the parent chapter in addition to customising your own chapter tactic. White Scars are not as meta-busting as Iron Hands but they're a very fast force where every single unit is dangerous in melee and are buffed by storm themed librarians that can throw chain lightning.
Non codex chapters are not in a happy place in comparison. They got some new units, shock assault and point adjustments, but have yet to receive doctrines, upgraded tactics, relics, stratrgems, traits etc. Space Wolves seem to want to run a lot of Wulfen, which...I don't really want to buy a lot of Wulfen. I still think Space Wolves are cool but the second edition codex that I loved as a kid didn't have Wulfen or marines riding wolves and I have't quite come around on them yet I may pivot back to Wolf rules when they get a good update, no way to know if that's Psychic Awakening or 9th edition.
So TLDR I think White Scars are currently better Space Wolves than Space Wolves. Also I do own Codex Space Wolves for 8th (bought it for fluff) but I think it's in a box in my home town in Australia.
