From what I can gather here are the basics. This is not a thorough list it is from the top of my head but this is what I picked up from my 6 month extensive search for my Dynamic.
Active= bare minimum, great value. Many don't have alloys some have optional extra. But no blue and me and no steering controls. Does have air con though and good safety airbags for an entry model. Something to think about if you have kiddies. Easily recognised as there is no chrome around the side windows and the handles are colour coded
Active sport= same as above. Bare minimum though it does have the sport styling (spoiler, skirts and alloys). It also has the sport seats I believe. This is only recognisable as the steering wheel has no buttons on them.
Dynamic= this looks like an active model from the outside except they have chrome around the windows and they also have chrome door handles. It's the inside that sets this apart. As standard it has cruise control, arm alloys, blue and me, lumbar support in the seats, centre arm rest, duel climate control, Boot light, Cool box in the armrest the list goes on. If you want toys this is the car to get
Sport= these have the sport styling, the sport seats, alloys, blue and me. A standard sport doesn't have duel climate control or a centre armrest. I believe earlier models weren't fitted with cruise control either.
All of the above have optional extras that when purchased were added if they wanted them. For example the 18 inch GT Alloys on the sport models. Or the sky dome (sun roof). Some have xenon lights. Some added cruise control to their sport models etc. The list goes on and it's up to you to find out what extras are on which car. That being said all cars have air con, and fog lights. I also believe they all have cornering lights. (At low speeds when you have dipped beams on. the fog lights will switch on independently depending on which way you are cornering. Turn left the left fog turns on and the other way is the opposite, when it does this it lights up the side of the road. Very useful and handy)
All of the above can be found with the variety of engines ranging from the standard 1.4 petrol (90 BHP) which is found often with the active models, to the 165 BHP 2.0 Multijet monster (diesel). Again up to you to see which engine it has. If I was you I'd hold out for a dynamic. The bravo is a fantastic car regardless of the spec and owning an active model does not in anyway effect the way the owner enjoys the car. It is each to their own at the end of the day. Some like simplicity others like gadgets (I'm in this category). But your question can only be answered by you. Being as you have the dynamic GP. It will only be you that knows whether you use blue and me and the steering wheel controls. Other than those. The active model should suit you just fine. Hope this helps anyone looking for a bravo.
Oh and if you look at cars after 2010 they have a facelift with slight bumper changes and dark headlights. These are stunning and I only wish I had bought a later model. But money was my issue. I'm unfortunately a cheap ass haha.
