Here's my opinion. I don't have experience with the Timemaster, but I have heard it is only decent at mulching (dry) grass. The Honda on the other hand is great and yes the NeXite deck allows you to mow when wet. If you primarily mulch, I would go with the Honda, but with close to a third of an acre yard the Timemaster would be helpful. If you have any questions about the Honda I would love to help, but it's tough for me to make a decision. I guess if I were you I would go with the Honda because I know it will last, cut well, and I frequently mow yards that size with my Honda. But that's just me.
