C152 is by far the better ab initio training aircraft (apart from its nasty wingdrop stall tendency). Stick with that until you have your GFPT.
Once you get your GFPT, step up to the warriors. You need to learn to adjust to a faster aircraft (you're not going to fly a 152 forever), plus warriors and archers offer advantages that are very useful in that phase of your training.
Far increased range, so you can do your Canberra nav without refuelling (which is now turning into a nightmare unless you have their special carnet card), you get experience operating a fuel system, more room for your maps, increased TAS to actually get somewhere, usually more avionics and comms to practice on, easier to taxi.
The 152 is better for ab init because it has much better 'feel' in the elevator, which can be quite jerky in a PA28, so its better to learn to trim in. Easier to land a 152, they're stronger, the attitudes are easy to remember, less overwhelming comms and avionics, cheaper obviously and you can see behind you which is handy to make sure you're climbing out on the extended centreline early on.
