Tom,
You are comparing a 2-stroke with a 4-stroke which are very different engines. I think it is like comparing apples to oranges although they both get you from point A to point B and will be probably be very reliable. You can read forever about the pro/cons of them on many different fishing forums. It all depends on “your” wants and needs as to which engine to choose.
Last year I had to go from a 2-stroke to a 4-stroke just because of the reduced smell of engine fumes. It turns out that the 4-stroke is very quiet at slow speeds and just nice to be around. EFI is also very good for cold weather running.
The bad part is that these engines cost a ton of coins.
