Hi Cloey,
Haven't been to Breezes, but we have been to Varadero.
We love Varadero, the beach is fantastic and everything is so close to town that you aren't stuck on the resort. A quick taxi ride and you've got shopping, restaurants, bars and clubs.
We were at Playa Pesquero in May, and although the resort itself was quite nice, I preferred the beach at Varadero.
Playa Pesquero is more remote as well so if you like to get off the resort there isn't much to do.
I think you'll enjoy Breezes Varadero.
