I definitely agree that the solid shirt looks better. I prefer to not mix three patterns (jacket/suit, shirt, and tie) and normally go with two patterns and one solid.
I like every piece you have shown singly, but none seem to be working well together in the combinations shown. I like the first tie, but it seems that the pattern is a bit close in scale to the houndstooth in the jacket. The paisley is a bit busy for the houndstooth and the waterdrop pattern seems a bit too modern for the traditional look of the houndstooth pattern. I think a solid tie with some texture or a stripe of some sort (preferably larger in scale than the jacket pattern) would work quite nicely.
