Yep I'm with djb, yoast is bloated and he has these really annoying graphic nag banners that try to sell his services in a blatant and overly promotional way - so I prefer all-in-one.
If you are going to purchase the pro plugin then before purchase, you can research other plugins with same features for free. Because for wordpress lots of free plugins are available online which has same and more features than pro or paid plugins.
