5* unit merged into 4* will yield a +1. Additionally, if you purchased Blarblade+ with the 5* and merge, the 4* will have it so as well as any 5* locked skills, something to consider.
Tailtiu is a solid blade time user, so I would consider a super-merged version. Just pick one without -SPD, and one with +ATK. Come to think of it, how many did you pull and what IVs anyway?
