Thai Airways Royal Orchid Plus - TG C to SIN or SQ

Flying C out to DPS. And chose not to take the non stop out of BKK cause I Am a fan of SQ and book the cook. So now I Can take TG down to SIN on a 777 or SQ. Since this is a short haul and no BTC. Who should I take? Of course I Do not need a bed, so space bed is not part of my decision. Just service and food I usually take SQ on this route or SK I have only flown TG C/F long haul or domestic. One more question. Taking TG F from HKG to BKK. Limo service is only available to hotel in BKK and not from HKG hotel?

Thanks
