please note that there are no such thing as "60 tourist VOA" You are mixing 3 different things up!
1. Visa Exemption
2. Tourist visa
3. Visa on Arrival (VOA)
From your text I understand that you mean 60 days Visa Exemption which is NOT a visa. It is a visa-free entry that allow residents from 93 countries to stay in Thailand for up to 60 days.
A tourist visa is also for 60 days, but applied for prior to travelling to Thailand.
Visa on Arrival (VOA) is eligible for residents from 31 countries. It is applied for upon arrival and grants a 15 days stay.
