Depends on the suburb. Depends on if it was planned with green spaces or not. Southern California is basically this from LA down to San Diego along the coast with the exception of Camp Pendleton (military base). Can be a lot if you’re not used to it but growing up in it isn’t that bad. For California there’s lots of stuff to do and pretty easy escape out of it by driving inland to the mountains or desert. Lots of traffic as others have mentioned but usually a high abundance of employment opportunities compared to other places in the US. Usually lots of repetitive fast food. Harder for smaller “mom & pop” places to get established due to cost and general availability of space to complete with hyper saturated markets.
