What is better for you?
The Truglo has a 5MOA dot. The PA has a 2MOA dot.
The PA has an integrated riser designed for an AR platform and co-witness. The Truglo has an integrated mount that will require the purchase of a separate generic riser (around $10 or so). Not having an integrated riser will make the Truglow more compatible with other guns you may have.
The PA has attached flip covers. The Truglo comes with caps.
The PA use regular AA batteries. The Truglo uses Type N.
With a riser, the Truglo is probably about 2oz less weight.
As far as durability and such, they will both hold up to a .22 and hold zero just fine.
