Advice needed from those who are familiar with long-term stays.

With tourist visa you can live 60+30, with Visa Exemption TH has 90/180 rule: you can live in Thailand 90 days per 180 days (if you don't have visa). Entries aren't limited.

Thailand did away with this requirement sometime ago - but some Thai Embassies/Consulates (Ministry of Foreign Affairs) still mention it. It will also pop up on some websites that have not have not been updated. In its place, if you use the land borders for Visa Exempt entry, you can only do it twice in a calendar year. There is no restriction if using airports - BUT, if the Immigration Officer (Ministry of Interior, Immigration Police) notes several past Visa Exempt entries and even Tourist Visa entries, they may want to see onward tickets, sufficient funds on hand, or in some cases will simply deny entry (Thaivisa.com has many postings by people denied entry at the airports, especially Don Maung). Thai Embassies/Consulates also require you have at least 6 months validity on your passport in order to apply for a Visa, but Immigration will allow entry provided the passport is valid for the length of stay.
