I have two and both have had equal use. I have the elcheapo Ikea one which is great when they're a bit bigger cos it's pretty basic, but it goes in the shower if you need to hose it down (or outside under the hose in our case).
I also have the Fisher Price Portable Highchair. It basically has all the features of a huge high chair but it has no legs and it either sits on the floor or straps securely to a kitchen chair. It has three different recline settings, a removable tray, is super easy to keep clean and it converts to a booster seat when they don't need the highchair anymore. Plus it's only about $125.
I have used it with both my kids since birth. We bought it initially because we only had a tiny unit, so it was perfect, but even when we got our huge house, it is so versatile that I still wouldn't have gotten a different one.
