Best wearable to maximize training peaks

Hello - looking for a wearable rec... I have the 1 year subscription and I'm looking to really maximize it, especially in the next 12 weeks and again in the spring. I am a generalist, but this fall I'm doing a half tri and then a marathon. Currently, I use a coros pace 2, and I'm happy with it, but I'm wondering if garmins, suuntos, a different model coros, polar, etc would be able to send more data to training peaks, this maximizing my subscription.

Thanks in advance.
