I took a Bolt ride in Pattaya for 60 Baht.
I checked the cost of going in the opposite direction by Grab and it was 210 baht.

For comparison purposes, I just compared to the cost of exactly the same journey in Pattaya with the 2 apps:
Bolt 63 Baht
Grab Car 296 Baht. After digging further, Grab seem to have some car options for about 118 Baht.

I've never used Grab in Pattaya, but have used it in Chiang Mai, where some quite attractive fares were offered.
