BPP, LSBF or Kaplan

Possibly not the best place to ask this given that most will be relying on the information available on here but has anyone experience with all three of these providers, specifically with regards to their online classrooms/lectures?
I’ve used BPP and they were pretty good but pretty expensive so I’m looking at other options for the next round. One thing that seems to be common with BPP and LSBF is poor server connectivity and lectures crashing etc. which i’d rather avoid if possible
