I can't give you any insights since i just started playing both of them, but imo ToS have simpler gameplay and good community, you can try google their discord.
On the other hand, GoW have more complex gameplay, its a bit more like Card Game with match 3 gameplay, try both yourself.
Tower of Saviors Just like Puzzle and Dragons but with a more mature graphics.
Tower of Savior was one of the biggest ones and probably one of the only few that could stand on its own. They introduced new mechanics that shook up the gameplay before PAD even tried to change things up with their tried and true formula.
I actually played a clone game first before finding out about PAD, called Heroes & Monsters. Most seem to be discontinued now, like Puzzle Trooper
​
Just a testament of how PaD has been doing it right for all these years.
Tower of saviors is very similar
