One good thing is the ability to bind new operators, so if you don't care to learn to read <> you could make it something else. Or you could have a local binding for Sequence so you don't have to use just Seq.
It's also possible to avoid almost all operators if you don't like them. There's nothing wrong with using a limited pool as long as you can get done the job!
I also prefer to name variables, functions, and parameters with nice clear names, and I've not found F# to get in the way of that.
I get your example of ‘seq { 1; 2; 3; }’ but list, array are not even shortened.
