WireGuard is faster, but has a 2 minute log of IP. This is not a big deal, but on Tor, it’s not faster.
Tor is slow due to latency, while WireGuard is faster due to throughput.
So you get no speed benefit but the minor downside. It’s a small point though to have this 2 min log.
I wouldn’t worry about it unless it’s a huge deal what you’re doing on Tor.
