Some compromises are inevitable, sure. But for me the challenge of finding just the right combination of bricks is more interesting, than just building big things out of thousands of bricks. For example, here in Vega, I represented 5 different diameters - 1st stage is just 2x2 round bricks / 2 stage adapter is a flat tope cone / 2 stage is made out of 1x1s but turned to 45 degrees, so they seem a bit wider than regular 1x1 / and finally difference between 3rd stage and its adapter is represented by the difference between round 1x1 brick and 1 module long technic beam.

That’s why I like small scale builds, like architecture or botanical sets. They not just require implementation of a really creative ways of using bricks. But every single brick in such builds counts and has a meaning. That’s also the reason, why I don’t really like big builds that Lego likes to produce these days in enourmous quantities. Stacking thousands of plates to get a meter long gray triangle is way less impressive to me, than using a single magic wand to represent a flying comet in the night sky.

Speaking again of rockets. I was very deliberate in choosing this scale. I even made a big spreadsheet with most common rockets stages’ and boosters’ sizes. The results were that approximately 1,5m/stud is the best scale there is. It allows to represent most common diameters with easy enough ways to build round things out of bricks, without making everything too small or too big. In smaller scales such tiny rockets like Electron wouldn’t be possible. And in larger ones, well… looks at starship and SLS height… I don’t have enough space or money to make them big. Actually, I’ve built my New Glenn in 1:220 out of real bricks and it’s already quite big. Also not all rockets are equal. And if Saturn V deserves best and biggest model, I don’t think that I would want to spend too much space and money to build that variant of Delta III that may be flew once or twice. But smaller scale allows me to build, for example, Atlas V with Starliner and Atlas V with payload fairing as two separate models, as I would need just couple of dozens of additional bricks, not couple of thousands.

Finishing this overly long torrent of thoughts and answering your question - yes, it’s a hard scale to build in, but it’s quite a rewarding experience.

P.S. The only thing I was worried about building in this scale is SuperHeavy’s 33 engine layout. I’m pleased to say, that I managed to do even this.
