For normal everyday road use I would say go with clinchers. They are available in a much wider range of sizes, from about 20mm to 47mm width. Touring bikes typically are set up with widths of 28mm to 38mm or so and there are a lot of excellent touring tires available in that size range. Some have special constructions to reduce the chance of flats, IMO desirable for a touring bike tire.
They will not roll as easy as good tubulars and are more likely to get snakebites if you let the pressure get too low. However easier to repair if you do get a flat and those with Kevlar beads can be folded so you can carry a spare tire, just like tubulars, which is useful when touring.
