Without a doubt, Fushida is #1 in all categories. I've owned Inverted Gear, Kingz, Keiko, and Tatami. They definitely fall behind in different ways, but they're alright in other ways.
I owned Inverted Gear, but I always felt like their arms should be a little bit longer for their A2T/S. Maybe I have really long arms, but I guess it still bugs the hell out of me. Also, I'm not a big fan of their ripstop pants and collars. The 350 gsm gis tend to stretch a bit. Overall though, durable, and you can find them from time to time at great prices.
Kingz is actually pretty decent. I own 2 of their gis, the V2 (1st batch of their V2) and their V3. The subsequent V2 batches were garbage, and even they probably will acknowledge that something went wrong. The other two gis are great. I personally prefer the fit and feel of the V2, and it seems slightly more durable since the V3 jacket lost a seam once (quick fix at the tailor for 5 bucks).
Keiko Limited and USA series gi is ok. Sizing for the limited sucks. I wanted to like it so badly, but it's an impossible fit for my arms. The body was decent, and the pants were alright (a bit wide, but I'm not complaining). For the USA series, their sizing changed a bit and the arms were slightly longer, but still too short, and the body was bigger. The pants were so big that I had to size down from A3 to A2. Jacket was A3. In the end, I sold both. I just couldn't justify keeping gis that didn't fit.
Tatami Estilo 5.0. I had high hopes for this one. It's actually very well built. It's a durable gi, no doubt, and will likely last a long time. However, the arms are too damn short. I don't understand why they would make the arms short, since the 4.0 fit perfectly. Oh well. This will no doubt go on the selling block once I'm sick of seeing it.
Fushida... 10/10 in all departments. I have 2 of them (GS and RS) and both are absolutely exceptional. If I had a choice between these and a Shoyoroll or almost anything else out there, Fushida wins by a mile.
