I don't think this should even be a discussion. If it covers costs well and your solutions work, discussing this doesn't matter.

I started with using .Net for a startup four years ago. Back then there were no Redis, NoSQL wasn't even a invented as a term, cloud servers were just a concept and scaling wasn't anybody's primary concern. In four years the only optimizations I ever did were done via SQL Server profiling or just by modifying a bit of code. I pretty much learnt .Net during this time and the sites I work for get pretty hammered at their peak times and handle well.

So yes from experience .Net is a good starting point. If you know the internals you can probably write and architect code that scales well too without falling back on NoSQL services. You won't need to go looking for complicated PHP cache solutions etc, you won't need to get in the trouble of selecting complicated frameworks. The whole setup gives you ease of mind.

No arguments against LAMP or other environments. Just that I always found .Net to be easier to work with!
