Which stats are better and merge which to which?

I have two 5* Lyn's and I am unsure which one has the better stats.

Lyn 1: HP: 34, Atk: 44, Spd: 37, Def: 30, Res: 29
Lyn 2: HP: 37, Atk: 47, Spd: 34, Def: 26, Res: 29

Help for this and explanation to determine which stats are better for future duplicates is much appreciated.
