I have a pontoon and there are alot of things i like about it>
#1. Easy to store
#2. Great for small lakes like in the Grasslands, creeks, and coves.
#3. Don't have to worry about getting as wet as in a yak
#4. More storage space
#5. Easy to accessorize
#6. will not tip like yaks
#7. You set higher than in a yak or tube and is easier to cast from.
Now the cons
#1. Hard to paddle; the drag and weight of the thing makes it hard to get anywhere fast.
2#. The wind if it is realy bad does play a problem, but if you stick to coves, creeks, and small lakes its ok.
3#. Easy to transport, mine fits perfect on the back of my truck with straps. They do make cargo baskets for it to attach to roof racks.
4W. Most folks grimess when you say pontoon because they have air bladders and could puncture but they are usually covered in the pvc material to help against this.
Since i have never owned or paddled a yak i do not know their pros and cons other than they are more expensive.
