Since I own both the 250ES, the 350X and the one you didn't meantion..the 250SX, I'm sure I can bring some insight to the table..
They have alot of the same strengths..but each has it's own characterstics as I'm sure you grasped.
To start the 250ES: it's obviously the utility of the three machines, truely an unstoppable monster. I find it the best choice when I want to do some advanced rough terrain riding. Mud, rocks, water, logs...nothing can stop this machine. Slow it down maybe, but the auto-clutch make is easy for the rider to get off the machine offer and push the machine and throttle control it out of whatever obstacle is attempting to hold it back.
The 350X: this machine has alot of the same great riding character but is lighter and more agile. The 4stroke engine gives a level of slow, tight spaces control the 2strokes struggle to give. It is at home equally on the straight open trail, climbing hills, and slow tight quarters like navigating thru trees. However when faced with an obstacle that requires the rider to get off and push, the manual clutch controls make it nearly impossible for a single person to 'drive' the machine out of a mud hole simply because your hands aren't free to push at the same time. Also the open disk brakes and chain drive system don't stand up well in muddy conditions..
The 250R is just the 350X on steriods. Faster and more than a bit twitchy..on tight, close trails a real handful to control since all it want to do it go fast. Not a personal choice of mine.
I intentionally left the 200X out..not because it's not a great little trike, but at 250lbs and being as I already own the 350X it just doesn't offer me anything! Not disrepecting this great little trike..just not for me.
The one you missed!!! The 250SX: while is has the same 250ES utility bones, is has a bit of a sportsters heart. Lighter and more nimble than the 250ES, but still having all the protective mechanics such as auto-clutch, enclosed brakes and drivetrain. It really is the best of both for the mixed terrain rider, a real sport-utility.
My advise to any 3wheeler owner with mixed riding interests is to make room for the 250SX, 350X, and 250ES. All three of these great machines..then let your riding mood dictate which to ride. No one machine stands out as being the better machine!!
