Ironically, often you get way faster speeds out on a RCG tower too. (probably due to few users), vs when in the city, where I often get pretty average speeds be it 4g or 5g.
It depends. Some RCG towers have a single channel (sometimes small 10 MHz bandwidth or large 20 MHz bandwidth) which all carriers share which will not perform as well as some native towers where up five channels are operated using CA (Carrier Aggregation) providing up to 100 MHz of total bandwidth. You'll see most of these in smaller towns. However I've seen RCG towers operate with multiple channels across which they load balance all customers (regardless of their native carrier) which are indeed pretty good (but AFAIK, RCG doesn't do CA but I could be wrong on that front). Those higher capacity towns are often in areas like beach towns where they expect lots of traffic during weekends and holidays.
