I've used them both fairly extensively. For me, the bottom line is Saitek, all the way. And although it'll maybe sound a bit strange, I kinda suspect that one's physical size comes into play on which one's more appropriate for the individual.
The CH pedals are fairly close together. If you're not too tall, and have relatively small feet (size 10 or smaller) then you'd probably be tickety-boo. But if (like me) you're over six feet and/or have size 13 EEE's, your ankles are banging together, and it's a wee bit difficult to find the null "sweet spot" where no rudder is being applied. Similarly, the CH yoke is probably okay for small hands, but with big, ugly paws like mine, it felt a bit too "toy-like". Then there was the "sproing" noises that the big, internal spring made, and the friction from a plastic shaft sliding in a plastic sleeve.
After a couple of years, I switched to Saitek
Saitek's pedals feel more solid and robust, and they sit farther apart (closer to RW), with a tension wheel in between. They also come with heel plates for resting your feet when bumbling along at cruising altitude.
The Saitek yoke is a nice, beefy thing with a solid feel to it. It glides -- even after several years -- and there's no irritating internal noises. Lots of useful buttons and switches, strategically placed, too.
The yoke comes with a nice throttle quadrant with full 90-degrees of travel (*very* important!), and more switches for things like parking brakes, AP disconnect, et cetera. The yoke also has a USB hub on the side, into which you can plug your pedals, an extra throttle quadrant, and so-forth.
So as I indicated, for me there was no contest. The Saiteks were superior, for my needs.
As a final aside, whichever make you buy, I'd highly recommend you fabricate a "ramp" for your rudder/brake pedals. I built mine out of two pieces of plywood, the size of the base plate of my pedals. Joined at the front (nearest me), I stuck a piece of two-by-four under the back, open end to provide an up-ramp, thus tilting the pedal toes up a bit more. Experimentation's necessary to get the right angle for your legs, chair, desk, etc.
Then I glued-on a slab of rubber matting to the bottom and voila, it stays nicely put, and provides me with that little bit of elevation needed because of my long legs. Now I don't strain to apply the brake when making a turn.
Hope all that blather helps somewhat.
