2.5 spacer ride vs Bilstein 5100 at 2.5

Wanna know how different the ride quality will be cause my spacer right now rides like a rock

 

Pretty similar, probably - they're both preloading the coil the same amount.

 

The spacer doesn't preload at all, a preloaded spacer does, this is a spacer on top of the stock set up you could also call a Strut Extention,

 

Its not causing the rough ride. You need better shocks and/coils.

Tacomas don't have struts.

 

But as soon as you ride in Tacoma when spacer is removed with same shocks and coils it rides nice and soft

 

No, it doesn't. I seriously doubt you have actually done that and had the vehicle properly aligned before and after.

Take the spacers out if you're sure they're creating this rough ride issue. Problem solved.
