Okay, my own punterish leanings are probably no guide to the preferences of UK-wads abroad, but perhaps the preference for overseas "stamina fests" is more to do with what's fun and looks good than what you're necessarily suited to?
Myself, given long-term opportunity, I climb my hardest grades on short, intense and crimpy boulder problems that suit a technical, static style. Yet, on holiday, I gravitate to the opposite: lengthy steepness, hurling myself between jugs with abandon. It's because when I'm on holiday, I'm on holiday, not at work. Of course I want a nice ticklist, but mainly I want to have fun: onsighting lots of different stuff and not risking valuable time on things that might need beta and a very patient belayer to red-point. And, at least in the areas I've climbed, the steep juggy routes seem most amenable to quickly bagging lots of 3 star classics. Such climbs are not necessarily easier, but their difficulties are mostly physical: the sequences are fairly obvious and the conviction born of an iminent return to the UK seems to compensate for a lack of native beta. Also... the look of those long steep routes just gives me the mojo to try them, regardless of what years in the UK have suited me to: a massive orange-streaked, tufa-strewn overhang just looks a lot sexier than 8m of vertical "scoop-of-death" crimpiness of the equivalent grade.
