Is this you? Do you feel like amp sims are great for writing, but you'd always choose a "real" amp for your actual record? If only you had access to a couple of great guitar amps, cabs and mics... If only recording these real amps was as quick and convenient as recording a DI into plugin... If only amp sims would sound as good as the real thing...
Good news: They do! Not the same, but just as good.
As always, it's not about the gear you use, it's about the sound in your head, your vision, your creativity. And there are always multiple different ways and different tools to get there.
When it comes to guitar tone, modern amp sims (virtual guitar amp plugins or Kemper profiles) can definitely get you there. That being said, we can see why you are feeling like they're lacking. There are reasons many people seem to love analog gear (and specifically analog guitar amps) more than their digital counterparts. But luckily, there are ways to make them work just as well as the classic amps we all love.
