The Sprint would be very similar to the standard Heinzmann, but slightly faster on the flat. The Currie would be very slightly better than both at hill climbing, but about the same speed as the Sprint. The Kinetics site doesn't show the legal low gear option, but they can tell you about it. One of this site's members has one. It runs up to 11.5 mph instead of the legal 15 mph, but gains on the hills because of that.
There are quite a few people who use the high torque 700 watt version and that certainly performs well on hills if you choose standard gearing, but don't choose the high gear 19 mph version for that will squander the hill climbing gain of those 700 watts. However, bear in mind that if you have a driving licence and get stopped for using an illegal version which in law is a motor cycle, you could endanger your licence given the number of laws you'd be breaching. It's a small risk, but a big penalty if you are unlucky.
Also bear in mind the 700 watt one has a short range, you'd need to check if it would be enough.
