What is better choice PAGP or LACP ?

2

I think, PAGP don’t support cross stacking that’s why LAGP is batter choice in multi-vendor network.

3

PAGP is a Cisco-proprietary protocol whereas LACP is open standard protocol.
Since LACP is IEEE based and supports cross-stacking, it is more often used to bundle the links and get maximum throughput.

Hope this helps!
Thanks!
