I would not be happy with a grill/smoker combo. It always feels like a suboptimal solution to both parts. I know finances and space dictate a lot about what we purchase but if you're an avid outdoor cooker, I'd suggest buying a dedicated grill or smoker or blackstone then saving up on the side to get the next one.
We have a grill, smoker and blackstone and we enjoy each of them for different reasons. If I need a quick turnaround, party is in 60-90 mins, blackstone or grill. If i have plenty of time to get the smokey flavor and I've prepped early enough, the smoker can be started well in advance and delivers a distinct flavor/moisture profile.
Of course, you can make a combo unit work but I think they often lead to more headaches. I understand everyone's situation is unique. I could do without the blackstone. It's nice to have a big griddle to do fried rice/noodle hibachi-style cooks for multiple families and it can be used for breakfast but it is a big item to be stored, uses a lot of gas and just isn't good build quality. It works for what it is and we enjoy the meals we take off of it.
I've had a PBC for 9 years and I've smoked a hole in the bottom of the steel barrel so it's on it's way out. Currently researching my next smoker and there are loads of options at every price point. I think the best price-value range is in the $800+
One day I'll get an insulated charcoal grill (possibly with rotisserie attachment) but they are expensive and i already have to replace my smoker. The PBC was an excellent way to learn how to smoke meats.
