I haven't flown business class on Thai Airline so I can't comment on that.
TG does not serve REP. Bangkok Airways has a monopoly on flights to/from REP serving Thailand.
TG business class is not that great. They are talking about upgrades but it will take some time. Angled lie-flat seats. 2-3-2 config in most cases.
