I have a Vision and a BGE. The BGE is better quality and holds heat better but also more expensive. it depends upon your budget.
Ceramic smokers are very flexible - I use mine as smoker, grill and pizza oven. it really is multi purpose in way other grills are not.
Regardless of make, get the largest one you can afford. You can smoke an entire brisket or sear steaks.
If getting the vision, do not get the combo gas/charcoal option. The gas does not heat up enough to use properly.
Always use lump charcoal and never use lighter fluid. Some people use a chimney starter but I use wax cube made by Weber.
Good luck on your new hobby.
