If is not necessary to stop or slow down, you are usually better off keeping up your momentum-- if by charging and slowing yourself down, you need to use more fuel to (for example) get up the next hill, you're worse off than neutral-coasting.
However, as far as I know, the HCH-II has a trick where you can barely tap the gas pedal and no fuel will be injected, but the valves will still be closed. This will still have slightly more resistance than neutral, but you're not burning fuel at idle either, so it's probably your most economical bet.

Where did you hear that coasting with all valves sealed drops resistance by 2/3? I do it often and it seems to me that resistance is a lot lower. The vehicle will coast just about as far in "valves shut" mode as is does in neutral.
Also, the term "tap" the gas pedal may be misleading. The way to cancel regen is to hold the foot on the pedal constantly and lightly. The more pressure, the fewer regen bars you see, until you get to no bars showing. At that point you're coasting with no fuel consumption and very little loss of momentum. Given this smooth coasting ability, I wouldn't ever consider doing a FAS in the HCH II.
