Depends on the terrain and what you are doing.
I have and old F150 I paid $1000 for. It's great for running and checking on things and picking parts up and bouncing through the pasture where it can make it.
There is no replacement for where a sxs can get you that a truck can't.
I'll give you another example. Let's say I drive 7 hrs out to wtx or 3 hours down south, with no cell service, rocks, stumps, and who knows what else. If my sxs rips a tire out I can run it. I may destroy a rim and tire but I'll get back to the truck and drive some where. Even if it isn't able to be driven I can walk back to my truck and go. When you out there and destroy a truck you are screwed. If a sxs or atv breaks down out in some remote place another atv or utv can drag it back or get it unstuck. When 3/4 tons and 1 tons break down out there it's a lot more headache getting them back to civilization be repaired.
I have put numbers together for the ranches I take care of for purchasing and maintaining a sxs vs jeeps or old trucks or what ever... the sxs will come out better every time. They have next to zero repairs and the resale is really good.
I'm not saying a sxs is the silver bullet by any means. If you can do a job with and old truck or a sxs, go with the sxs. There is no replacing each one individually though. If you need a truck... you need a truck. If you need a horse... you need a horse. If you need a sxs, you need a sxs. They are each different tools for different jobs when you have to have them.
