OK, so a little background.
I've owned twice the GR20/GK3 combo (GK3 had been installed on 3 different guitars), I own the GM800/GK5 combo (GK5 had been installed on 3 different guitars and now it's installed on another one) so I can only compare the TP with these.
In terms of single note tracking beats every other guitar synth I've owned hands down. You can do really fast passages that simply cannot be done with the rest of the bunch, not without false note triggering etc.
It has less system/hardware settings to adjust than the rest, but it does the job.
Now, In terms of playing big chords, especially if muting adjacent strings is required, out of the box it's a little worse than the rest, BUT fooling around with the hardware settings and adjusting the playing, gets the job done.
Personally, I am keeping the TP, this is what I use nowadays so I recommend it for anyone that is looking for a guitar synth to use it with VSTs. For live use obviously the GM800/GK5 seems a better option unless you want to depend on a computer.
The software is OK, a bit steep learning curve if you are not familiar but learning how to adjust the hardware settings is more than enough (you don't have to load your VSTs through the TP software).
The installation is easy BUT, having to permanently "glue" one of the mounts on a specific guitar is a big minus to me. They should give the users the capability to also screw the hex pickup and be able to adjust the height whenever is needed.
I had to add a shim to one of my guitars in order to get the needed string clearance.
And since there is no way to adjust the height after the installation, I recommend you do your homework first, decide which string gauge you are going to use first. Because, if for instance, you start with 9-42 and you want to change to 10-46, there is a chance the signal will be so hot even with the sensitivity at minimum settings, you won;t be able to set it properly unless you increase the string action (or add a shim if your guitat is bolt-on) which, well, it will change your instruments playability.
Also, I trully believe the instructions on setting up the strings clearance is plain wrong. Fishman say just leave 1mm gap between the pickup and the strings. If you do that and start playing, say, in the middle of the freatboard or at the last frets, the signal will be getting overloaded which increases the chance to start getting artifacts (dying mice sounds etc.), that's easy to see if you have the TP software open, monitoring the sensitivity bars and playing across the freatboard. My advice, do it like you would it if you had the Boss/Roland guitar synths; Adjust the sensitivity with the last frets pressed. So. 1mm gap between the pickup and the strings with the last frets pressed.
The battery life is great, but in real life I don't think it's 20 hours, probably 20-25% less which is still great.
They should have already come out with a revision and change the USB port to USB-C instead, if you ask me, because it's a PITA to have to deal with cable orientation on such small plugs (and if you make a mistake, it's easier to destroy the USB port of the transmitter).
Can't really comment on the range as I have a USB extention cable so the transmitter is 2m tops away from the receiver with no obstacles in the middle.
The latency is minimal which is great since it's wireless (warning, I am talking about the clean signal of the hex pup compared with the dry signal of the guitats pickups, I am NOT talking about VSTs, that's a totally different story, and it depends on the VST itself, PC and audio card, buffer sample settings etc.)
All in all, for people that need a hec pickup to use VSTs I recommend it,
