Who to consolidate pensions with?

I've got four employer pension plans that I would like to consolidate so it's easier to keep track of it all in one place. But I'm a bit at a loss as to where to put them. None of them are especially big; it's one plan I had with my employer throughout five years of university, and one each for my post-graduation employers.

I really want an easy and accessible way of viewing it all, and so as a result the likes of Pension Bee and Nutmeg appeal. However, at least with Nutmeg, they seem quite expensive.

My current employer's scheme is with The People's Pension. Looking online they don't seem to rate very well, so I don't know if I want to merge them all into that.

Any ideas for a good, user friendly online/app platform with reasonable fees and decent performance?

For what it's worth, the pensions I have are with Zurich, Aegon, Friends Life and The Peoples Pension for my current one.
