I've run jon boats for close to 40 years. Big ones little ones. Everything mentioned above holds true about jon boats.
I run the big river here with an 18' jon coupled to a 35 hp Go Devil. Nice rig. Plenty of get up and go with the motor.
However, for smaller rivers and marsh situations, I've finally settled on this rig:

It's a 14 ft V-bow Lowe, though Alumacraft makes something very similar. On the back is a 9 hp Honda Go Devil. Very rowable. Very pullable through weeds and shallow water. And the 9 hp has enough guts to plane this rig upstream when loaded down with 'coon in the front end and gear.
Note the spotlight on the bow. I've got it mounted right above the running lights. It's actually a tractor beam from Farm & Fleet. Electrics are run back through 1/2" pvc glued to the inside hull back to the transom where I've got switches for running lights and spotlight separate. The spotlight has a carriage bolt running through it, and this can be inserted into a hole I drilled in the bow plate with a lock washer and wingnut. That way it can be removed when not needed. I've got an outlet bolted underneath the front seat to plug into.
Also makes a dandy duck hunting rig.
Take a look at the back of the transom. I've got two U-brackets bolted/glued on either side that take a pair of 12" wheels. The wheels can be locked down so you can pick up the bow and pull it across a boat landing if the landing is full of fools trying to launch/pull out at the same time. Then they can be swung up and locked in place when you're in the water or on the trailer.
A real advantage of the V-bow over the jon boat front end is the ability to load up the front end with weight and not have to worry about burying it in a wave or shipping water over the front end when shifting weight.
Also, when motoring at night, when I run most my lines, I can careem off a log or snag with the V-bow, where with a flat nose jon boat I used to come to a sudden halt when smacking anything in front.
Here's a pic of a place we camp at. Sweet spot bigtime. Shallow water, but this rig floats right over the sand.

Best bet is to find someone close that will allow you to ride along and get the feel of it that way. Anyone in this area is more than welcome to contact me for a ride this summer.
I'll also plug Ron Paul's Go Devil dealership in Fox Lake for being an upfront guy here in Wisconsin for making sure you're getting what you want and also does well with trade-ins.
By the way, I've been running Go Devils since '87.
