Frohan, I don't believe that it's fair to generalize regarding Epic quality. Epic makes good skis. They've got different design ideas, layups, and layers of quality control from FEnn, which complicates matters.
I've never owned an Epic ski but have paddled several in races and in training (I've owned Fenns, Custom Kayaks, Thinks, Findeisens, Futuras). I don't believe that it's the brand per se, but the layup that poses problems and leads to generalizations. Specifically, my HUNCH is that the Epic Ultra layup kevlar/core ski is quite susceptible to hard knocks, being squeezed by too-tight rack straps, etc., while the similarly priced FEnn carbon ski stands up to similar abuse because of what seems like a solid composite construction. I've had two carbon FEnns with soft spots, though. The Epic Ultra layup is about 3-5 lbs lighter than the carbon Fenns. Is that trade-off (softer skin vs weight savings) worth it? to some it is.
However, the Performance layup Epics seem a better deal than the fiberglass FEnns. I believe prices are ballpark similar, the Epics run about 32 lbs and the glass Fenn's run heavier (a friend in Florida has a 40 lb glass Elite, yikes). Both layups here are probably fairly durable. Remember the two Epics that got caught under the barge in NYC last year? The ultra was trashed, the Performance only needed a new rudder because it got snapped off.
The Epic all carbon elite layup skis are probably similar to the carbon Fenns in durability, I would guess, about 7 lbs lighter but more expensive. Both with stiff resistant hulls.
Epics have better finish if that matters to you.
The Epics and FEnn Elite are all fast skis. Outside of a tow tank, they're probably the same performance. But, If the V12 is 1% faster than the Fenn on flatwater with the scupper closed, then just ride its wake in a Fenn for a 5% savings.
Which to get? Look at their comfort for yourself, how you like the other things like footplate, rudder, etc. The Epic skis have lower gunwales and many think that they are easier to get into - the flipside is that the Fenns might have a drier ride. I can't under-emphasize the importance of comfort, too.
How much do you want to spend, i.e. what boat weight are you looking at? Since I don't like to treat my skis with a kid glove, I would opt for either the Epic Elite carbon layup, the carbon Fenn, or the Epic Performance by price point - all else being equal, and that's just my opinion based on minimal facts and from what I've seen.
Both Epic and Fenn are small companies, too, it's not a Wal Mart vs local family builder issue. Epic just SEEMS big because they've had an advertising/marketing plan for years while Fenn is still working on putting content on a website. Both companies take advantage of low wage areas to build skis - Chinese vs S. African, take your pick.
Avoid supporting brand-bashing of Fenn, Epic, and Think and Huki, Custom, etc. They're all trying to make good products and advance the sport of ski racing, and for that we paddlers should be thankful.
And remember, these companies are not just "companies". They have owners and employees with spouses and children to support, too.
