seen the K1 running at my club quite a bit and hear it drawing a lot of comparison to the tamiya 5something and the feedback is generally good. I myself have not built or run one but I have built an SX3 and have to say the build was smooth and easy, and am absolute pleasure. everything fit together well and the manual was clear and easy to understand.
Cost wise, your looking at around £300 and many K1 drivers will tell you that there are essential upgrades out the box depending on the track. There are also many many fine upgrade options available for the car, strangely though they are all still purple and gold which moves away from the original sleek black stealthy look behind the K1's original design and parts which to me is a bad thing
The XB4 is a fairly new entry to the 4wd market as it is Team Xrays first foray into the 1/10th scale off-road arena, from what I have seen its a decent car with a superb build and great manual. There are few option parts available at the minute as you get nearly everything in the box, roll bars, shock oils and diff oils are all included in the box and so far Xray has shown some superb customer care by releasing a free upgrade kit to owners to strengthen some parts that were deemed as weak by racers.
The flex system on the chassis of the XB4 allows you to adjust for different track conditions without the need for additional parts or chassis by simply changing the positions of some screws. At around £320 for a kit you are looking at an expensive buy but as near as I can tell there really isnt much else you'll need to buy for this car apart from maybe some springs and tires.
compared to say a Durango 410v3, @ £280. out the box has plastic wheel hexes, plastic shock collars and no diff or shock oil included, those few options there will almost make up the extra cost of the XB4
I cant really comment on the others as I have little to no exposure to them and haven't looked at the models myself but as is always the case a massive "pro" for any car you may purchase will be how well its supported at your club in order to get advise, help and tips
