I boght my first pari recently and did a fair bit of research into this. given the details you provided, I am going to lean towards sugesting the neoprenes. Here's why:
1 - You said you fish all 4 seasons, just like me. Neoprene's will keep you warmer in the winter. The down side to them is that they will keep you warmer in summer as well. In the summer i am planning on just wearing a pair of board shorts and a synthetic t-shirt under mine.
2 - I have head that neoprenes are a bit more durable. This is good for us new guys, just becasue we lack experience wearing them.
3 - they are (usually) a bit cheaper
4 - i'm sure most of the vets on tis board will agree that this last one is important... they offer better flotation in case you take a spill, you have more floatation in them (provided you have your belt on tight), and you are less prone to hypothermia in prolonged periods of exposure.
Breathables aer great, and when I can afford them, I will certainly be picking up a pair to wear on those hot summer days where I am not more than knee deep. They are also more comfortable.
Overall, I think the neoprenes are jsut more versatile for a first time buyer.
