I’ve been using the tucker alpha hybrid brush with rinse bar. Some houses, the pressure seems kinda low,(rarely an issue) but take the advice from @Johnlee on that. It’s been a good brush, I highly recommend it.
And the gooseneck really just depends on if you need it or not. Look at the most common jobs that you work on. The tucker swivel adapter is all I use, no additional gooseneck needed.
