Been playing for a while, and IMO:
- Ttar fits better than ever thanks to disabling weather and freely chip common archetypes. It disables snow/rain/sun and is strong and durable enough to consistently do so, while keeping in check some threats of OU (Ursaluna, Moth, some slow variants of Gambit, the slow bros, and so on), and pokemon that can check it don't like being knocked off. Paired with G-Weezing, which completely walls Tusk, creates a very consistent way of preventing and removing Weather and Screens/Hazards. Also been using roar variants and they work fine since there are so many set up sweepers now.
Grass tera allows you to beat or cripple most Ogerpon Variants, Wake, or rain sweepers in case you need a backbone against those teams.
- Ogerpon-Hearthflame is a tad too strong for how easy it can set up, specially in sun. The other forms are not as strong atm.
- Ursaluna atm is balanced because the low spd is exploitable, but I get that it may be frustrating to play against when you don't have a dedicated wall for it while also playing mindgames with Bloodmoon and Moonlight; also people underestimate Vacuum Waves damage. However, non CM variants lose against strong special attackers, Empoleon, Clefable and so on.
- Tail Glow manaphy is fine, but Acid Armor + Take Heart variants often need 1 or 2 turns of set up to be unkillable specially with tera.
- People are sleeping on Scale Shot Regidrago and G-Weezing though
