It really does depend on what you want to do after you've qualified. Modern microlights are highly capable and relatively inexpensive - but limited to pilot and one passenger and day-time VFR only operation. But they are huge fun.
If you just want to fly for fun, on your own or with a mate, then go micro. If you have wider ambitions, then learn on a "spamcan".
You've had some time in a Cessna, so I'd also suggest you go and do a couple of hours in a fixed wing microlight so you can compare.
