Tuxman introduced WoX (stands for something- I saw it somewhere, but I can't find it right now) in the
Listary 6 thread, and I started to look into it. I'm running it and FARR right now, and I like features from both.
FARR has more options for customizing your search heuristics and such. It also has everything built into the application, and you don't need any dependencies. WoX needs .NET (not a big deal as everyone on Windows has it), Python, and Everything.
Both of them have a lot of options in regards to interface design, so that's a wash between the two. Both can be portable or installed.
The plugin syntax for WoX just makes more sense to me, but I'm sure it is a matter of developer preference. WoX is faster at searching, but this is because WoX farms out a lot of its search capabilities to Everything. FARR allows more customization of the heuristics and search behavior, which is a definite plus- the only nod to this functionality that WoX provides is the ability to pin a search result to the top of the search, so that the next time you search, it will be favored. Not ideal. But in its favor is the fact that WoX is open source- this makes it easier for me to understand things about the software, which is a bonus.
It's definitely not an instant win for either which is a surprise- I've given other launchers a try, but WoX is the first one that I've seriously considered. I'm running both in parallel, so I guess I'll make a choice as time moves on.
