Evaluating Hubspot vs Attio for a Hybrid PLG and B2B GTM Tool Stack at Our Startup

Good morning. I lead GTM for a start-up and we are constructing our foundational tool stack. The model is primarily PLG, however there is a need for classic selling and development of partners, which will resemble a typical B2B process. I am about to evaluate whether to just march forward with Hubspot, which we already have been using in a very embryonic mode, or evaluate moving to Attio which initial research suggests may better fit the overall GTM. NOTE: The decision whether to go all-in on Hubspot or to leverage a bespoke solution for marketing automation / messaging / in-product is a variable we have not yet locked down. I do not see us considering a heavy SFDC option. If you have some practical experience with these tools, I'd appreciate a short conversation or direct DM. Thanks in advance.
