Guess it depends on the VST. The marching arts use MainStage as a staple, and their onboard sounds are shit. They had an update recently that drastically improved/replaced a lot of piano sounds, but they’re recording/pop tune pianos. Very good, but don’t act like a piano through the dynamic range and release. There are some good piano VSTs, but you need to purchase multiple VSTs to get all the right sounds you want. I may use one piano VST for one movement and a different high quality one for another movement. Through my experience with a variety of industry standard piano VSTs played through any number of industry standard DAWs, I still haven’t found a setup that perfectly matches the nature of playing a piano and how it reacts to your fingers the way a Yamaha piano patch does. Take a Yamaha piano patch and put it through whatever filters you want, and you can get a highly realistic player experience with all the mushy gushy reverb or anything else you want.
