Op, I believe you enjoy the open soundstage of HE6se V2. Newer Hifimans have more open and larger soundstage. If you really like soundstage, you should try those out.

It is a balance between presence and soundstage. Some headphones like Sennheiser HD6x0 series have forward and present mids/vocals, but small soundstage. Other headphones like newer Hifimans have open and soundstage, but mids/vocals sound lean and recessed.

HE6se V2 is in between. It's vocals are reasonably forward, and soundstage is also average. Nothing wrong with that. Good balance for forwardness and soundstage.

And bass is just separate attribute that really stand out on HE6se V2. Punchy and impactful.
