So quite often judges make their decisions based on "feels" and then go out of their way to be nice to the other party so they don't appear biased. You can imagine the poor self representing party that has a strong case but is automatically disliked by the judge for not playing the game properly and basically has no chance.
I think you misunderstood. It is not based on "feel" and the greater procedural leeway they provide the party with the perceived or actual weaker argument is not for appearance sake alone. A judge wants both parties to make their best case and if one party fails to do so, they try to help them along to achieve it.
