I used to do every thirty days, sometimes for a few months when work was scarce. Never got questioned and I used to border bounces everytime. It wasn't until ten years after I moved to Thailand that I got Red stamped. So did ok. Still let me in for thirty days, so went back to my country and got a non O multiple entry.
As far as I believe you don't get an entry card, can't remember the TM number, anymore. Last time I got one was in 2018, I think. If you turn up with an e-visa you just present passport and e-,visa, then when you get accomodation, wherever, the owner has to fill out a TM 30 online.
I worked out of Udon Thani for eleven years travelling long haul at least half a dozen times a year, plus domestic flights to DMK., then later Suvarnabhum. The flying didn't really bother me, it was all the security at airports that go me down. Mind you that's is better than another
All depends how long you intend staying, if only ninety days, no reason to bother doing a visa run for the sake of 1,900 baht. Probably cost you more than that in travel plus expenses.
