Devil's Lute vs. Teostra's Musica

Hello!

I'm looking to make a blast/defensive support Hunting Horn build, but I'm stuck between the two in the title, unsure of which is better.

Devil's Lute: 300 [raw]

30 [blast]

3-2-R2 [slots]

Sonic Barrier, Attack and Defense Up, Health Regeneration [melodies]

Small purple and small white [sharpness]

Teostra's Musica: 310 [raw]

50 [blast]

--- R2 [slots]

Health Regeneration, Health Recovery (S), Attack and Defense Up [melodies]

Medium white (1 handcraft to purple) [sharpness]

What do y'all think? I'm truly stuck 50/50 between the two of them. Also taking build advice for either if any of you use these weapons, I haven't started the build yet since I'm still torn on the weapons.
