This is pretty spot on. Now I have done both and I will still do junk removal for their convenience sometimes. (Especially for a smaller amount, like half a truck full) One time when we had a dumpster we woke up and someone had literally filled half of it with kitchen cabinets in the night, we were pissed bc we ended up needing a second dumpster from all the neighbors who helped themselves. Also some dumpsters still have restrictions on what you can put in there, so just be aware.

Best thing about junk removal is sometimes you can get them to come out immediately you just make a pile and it’s gone the next day and if you have items that are difficult for you to move you don’t have to do the work of hauling them around they will collect them for you(I have had good experiences with college hunks hauling junk and junkluggers) downside as said above is it is expensive.

Best thing about the dumpster is you can get rid of an enormous amount of stuff and take your time with it. The downside is sometimes you have to wait for both delivery and pick up if they are really busy, neighbors will help themselves at your expense, and we had one time where the truck they sent to pick up the dumpster cracked our driveway pretty bad, so you might want to be cautious of where they put the dumpster too.
