Productboard vs Dovetail vs BuildBetter for product feedback at 100+ enterprise accounts?

evaluating platforms to replace a homegrown notion & spreadsheet setup that broke under volume, and would appreciate real takes from PMs who have run any of these at similar scale.

we're at 110 enterprise b2b accounts, running around 250 calls a month between Gong and product discovery sessions, plus around 1500 support tickets that currently get triaged in Zendesk without ever feeding back into the product loop.

shortlist is Productboard, Dovetail, and BuildBetter, and each is being pitched as the right call for our shape, but the public material reads similar enough across the 3 that it's hard to tell where the differentiation lives without operator scars.

specifically trying to compare:

- theme clustering accuracy across mixed call + ticket inputs

- integration depth with linear for converting themes into roadmap items without manual relay

- pricing at our volume since the pricing pages is no longer honest above 50 seats

- and which platform's PM hours fall versus which one just gives us prettier dashboards

if you've gone through this eval at 75+ enterprise accounts recently, willing to share which one shipped and which one had a hidden constraint that broke the model after onboarding?

thanks!
