1 Big server or Multiple small ones

Ahoy everyone!

I will be running a BungeeCord network soon with a total of 4 servers:
Hub: 4 GB (RAM)
Minigame: 8 GB
Potion: 8 GB
Build UHC: 8GB

I wanted to know if someone can clearly tell me what are the pros and cons of either getting 1 big 32 GB server or multiple small servers: 3x10 GB + 1x4 GB, for this BungeeCord network, which method would work best in terms of latency, lag resistance, overall performance of the network etc.

Thank you for the help!
