I made exactly this decision almost a year ago and bought the stumpy in the end. I think it very much depends on what you want it for. I wanted a do it all bike and I decided (from trying both bikes, speaking to people with either bike or that had ridden both bikes and from the girly opinion that colour matters) that whilst the remedy would be more fun on jumps/drops/dh riding it would be a lot less fun on the xc endurance racing I do so I went for the stumpy and have not regretted it.
I have done endurance races, xc races and downhill races on my Stumpy and whilst I except that it may not be the perfect machine for each of those things independently it is a very good all round bike. I take it out dirt jumping, xc riding, uplift dh riding and even took it to the Alps and across Italy riding DH tracks.
A few people I have met along the way have queried my choice of steed especially when stood in an uplift queue, “don’t you know that bike is only 140mm and designed for trail riding” type comments are heard fairly frequently! All I have to say is that it is more capable than me and if I am willing to ride off that drop then I am sure it can cope with it!
The only criticism I have is that more sturdy wheels would be nice (I have put small buckles in them off big drops), although I like the light ones for xc racing, so I think the bike is the perfect 1 bike does it all for me. I know people with the rememdy who do less xc and they have the same 1 bike opinion as I do.
Ride them both and then decide!
