Which is better both are workhorses 

Seaguar Invizx 

 

One is not really “better” than the other. 
InvizX has much more stretch than Sniper. 
Sniper’s diameter is just a tad smaller at certain weights but not overly so. 
 

Some guys like the excessive stretch of the InvizX for certain moving presentations but not as much for certain bottom ones. 
 

I use Sunline’s Sniper and Shooter exclusively for everything except for 2 presentations, not because of being sponsored, but because of how it performs overall for my style of fishing 

 

Best thing to do is get a small spool of each and decide for yourself

Interchangeable to me. 

Sniper.

 

I use both extensively, Invizx for spinning reels, Sniper for the pigs.

 

Don't like the abrasion resistance of Invizx as much as Sniper, and to be honest both suck in comparision to cheaper P line Ultimate Fluoro, but that stuff is rope thick.   

 

Sniper.  If I want streatch I have big game.
