Of the limited replies, nobody has recommended you use tubs. I think you have your answer, even if it isn't the one you wanted!
After my early mistake of thinking you were asking if you should go from tubed clincher tyres to tubeless clinchers I still didn't realise you were actually asking if you should swap from clinchers (tubeless) to tubulars (i.e stitched up casing glued to the rim).
My mistake the second time probably arose because I didn't think anyone would be mad enough to use that set-up for leisure/holiday/touring type riding. Why would you? Just a single puncture and that is your day essentially over, the fix is not really a roadside task (someone will doubtless be along shortly to describe how they removed the glued tub, unpicked the carcass, fixed the punctured tube and then re-glued the repaired tub to the rim in just 15 minutes before continuing their ride.....
).
I suggest you forget tubs, if for no other reason than if it doesn't work out for you then the option of fitting clinchers is not open to you without re-rimming the wheel. If tubeless is working for you then stick with that, but I would choose and recommend traditional tubed clinchers as these are the most reliably fixed in the field in real world conditions. This is the kind of dependability that's required when touring or riding in possibly remote areas or long distances when completing the ride is more important than a few theoretical saved seconds or a subjective difference in 'feel'.
Sorry if this isn't what you wanted to hear, but that doesn't make everyone else wrong.
