Are you not using the upgraded vive strap already? Having used one I can say it feels way better than my Q2 and is on par with the Pico. My Q2 has the default strap and the reason is sucks and feels heavy is it's forced to put all the weight on your face. The Pico by comparison is lighter but also feels lighter because it shoves the battery in the back and counter-balances the weight of the headset. It makes a huge difference, your head is basically a lever and unbalanced headset straps means you have all the weight on one side of the lever. It's going to feel way better balanced, even if it's not battery balanced and just a better back of the head strap. 

As far as the pico software goes it works as good (maybe better?) than ALVR with my Q2 but that could just be that it has it's own settings dialed in better by default. Allegedly the Pico 3 Link and the Pico 4 use the same streaming software, the thing that turned me off to the link is that for some reason the audio and mic are completely broken and don't work with the DP mode and only work wirelessly.
