There are canoes, and then there are CANOES. There are yaks, and there are YAKS. You can't really compare them unless you decide how you want to rig them and how you want to use them. This question comes up often enough that I have some boilerplate text on file and will paste below.
Welcome to BR.
Really, only you can answer that question. Some types of small watercraft (canoes, kayaks, bass raiders, float tubes, pontoons, inflatables, etc.) are perfect for some people. No one type of small watercraft is perfect for all people. In selecting whether you want to get a canoe or a kayak, you need to make a list of your needs, and then determine which craft is the better fit for you. Some of the factors to consider:
Stabililty and standing capability (moving around, landing fish, another person or kids or dogs in the boat, standing to fish, etc.)
Cargo/gear storage (how much stuff do you want to take)
Inboard storage & handling (canoe) versus handling things in your lap or over the water (yak)
Seating position (usually, but not always more upright seating in a canoe vs. legs-out in yak - have back problems?)
Vessel weight (how much can you lift/transport)
Transportability - to the water and possible portaging (do you have a truck, trailer, going to car-top, need to portage, etc.)
Ease of paddling
Will you want the capability to motor it?
Manueverability
Type of water (lakes, streams, white water, etc.)
Number of people in the craft
Stay mostly dry or don't mind getting a bit wet
Length of voyage (couple hours or a couple days)
Etc.
Once you answer those questions based on your own capabilities and needs, you'll come closer to chosing either a canoe, a yak, or a hybrid. All are great watercraft in their own ways, you just have to find the best fit for YOU.
I faced the same decision as you are tying to make now but I was open to all types of small watercraft from float tubes up to bass boats. The best solution for ME, was a heavily accessorized canoe. I only fish my local, small (1.5 to 201 acres), no-wake lakes. Some of these lakes don't have boat ramps. I needed something car-topable without a special rack, modular, very light weight, with as much capability as possible. I wanted stability so I could stand and fish all day, lots of inboard storage, motorized, and little to no maintenance. I didn't want to have to buy a truck or other tow vehicle, I didn't want to consume a garage bay or driveway space with a boat and trailer, didn't want high expense and high maintenance, and didn't want to use gasoline power. Taking everything into account, I ended up with a canoe, trolling motor, and outriggers for stability.
