When I really need one, Transient Master from NI works great. ...the whole concept though was made by SPL back then, so they know it the best, but if you have Komplete for example, NI one works as good.
...also BitterSweet from Flux works great. Less control, but it's free.
Yah I heard great things about the transient master plug thanks for the suggestion! And about bitter sweet I actually downloaded it and tried using it and it was way to buggy on my project , like sometimes I would press play and the plugin would play back the sound like totally bypassed as if I didn't even shape the transient lol.
