Moving on from full frame Sony A1 goodness to OM-1 reach and versatility of m43

So this will be about my choice or rather experience with both systems using them side to side and eventually made the maybe unpopular choice. Lets discuss or let me explain because if you talk about this then there are two camps shouting to each other that full frame is better and the future, the other side will shout its all about versatility and the ability to shoot and be flexible in any shooting condition. Rather get further and get the shot than give up halfway there.
