How is Rogue Genesia?

I have my eyes on Rogue Genesia, and it looks really unique, but how much does it difference itself from other survivorlikes? I have a few questions for people who played it and can help me compare it to some games, the ones I played and liked were: Vampire survivors, Brotato, Halls of torment, Death must die, Soulstone survivors.

Questions:

1. How does it hold against other games, does it feel like it's own thing?

2. How much do classes difference gameplay wise?

3. How is overall variety?

4. Curious about the equipment system, does it feel good and is the loot gathering fun?
