I agree but it's hard to measure when the UX difference is big enough.

But provided that two products have the same feature set, as a genera rule, the one with better distribution will win - nevermind whether the quality of the features (UX) is better or not.

True, the churn can be higher for buggy products. But it might be difficult to get off from it - integrations can't be copied, data export is not ideal, lots of time and money invested (in both the contract and training), not sure about whether there are better alternatives (it's why some end up with buggy products in the first place - bc the lack of proper testing) etc. That maintenance cycle can be a year or more, depending on the commitment.

Product managers are obsessed with quality because it's what they can control. Pricing is much more difficult in a big enough company. Hell, it can even be difficult in very small companies.

Adding a feature usually feels like adding value. Changing pricing can feel like losing value/customers. Both can be untrue tho.

In general, compete on quality if you can't compete on price.
