I don't know for sure about 4x4
WRM, GTS2M, MGC, or YJ mini
but what I've been told by fast big cubers is that for 5x5, the best is still the Valk5
The Valk and MGC are tied, but I like the MGC way more (and so do a lot more people)
the best 7x7 is still the Spark.
The Spark and MGC are almost tied, but I think the MGC
1) performs better
2) is ~$20 cheaper
3) corner cuts better
4) catches less often if you tighten it
The Shadow v2m is an option behind the MGC6, but it's not actually better (but it is slightly smaller) and it's more expensive so there's not much point in that one.
The Shadow V2M is miles behind the MGC, in terms of value and performance.
It's been a while since I've been actively involved within the speedsolving community. What notable WCA puzzles have released in the past year or so?
Gan 12 (MagLev and Leap), WRM 2021, WRM 2021 Maglev, RS3M 2021 (MagLev), Dayan Nezha 5x5, Tornado V2, Qiyi Clock, etc. Look in the "Best Puzzles" (or something like that) thread to find the best puzzles today!

Is 6x6 hardware satisfactory now?
The MGC is still the best 6x6.
Is there a square-1 better than the Volt M,
the MGC.
is the QiYi Clock still dominant,
Yes.
is the Valk still the best 2x2
MGC elite is the best non-discontinued one, (Valk is discontinued), but I prefer the MGC Elite or any of the Gan 251's (Pro, Leap, Air), not the V2 or the normal one.
