I switched from 818H1 21° to TS2 19°. H1 is a great hybrid but TS2 plays like a small 5 wood and very long and forgiving.
All in all both are great and no hook machines like most of the hybrids. I was a long time 5 wood player and the TS2 is the right choice for me. If you have a more sweeping swing the TS2 is something for you.
If you who hit down on the ball, the TS3 is better but less forgiving.
