よっぽど

[Andromedashun]

退屈してくすぶってるより刺激があってよっぽどいいぜ！

Having an stimulation is much better than boredom doing nothing!
How is the て form work with よっぽど?

 

[Toritoribe]

あって is associated with いい（ぜ）. よっぽど is an adverb modifying いい.

 

[Andromedashun]

I see. So is it like あってもいい?

 

[Toritoribe]

～てもいい means "it's no problem/OK ~", whereas ～ていい is more positive "it's good(/better) ~" here.
