I'm still undecided on this question to be honest, I really like both and I think equally.
Lowtech firstly is just SO much easier in terms of maintenance for me, especially because I do prefer to use at least 50% rainwater in my tanks. It's a more chill way of doing things.
There are also so many great niches of it to experiment with like blackwater, emergent plants/pond scape, a river/stream style that's just as interesting and good as high-tech and even just normal lowtech you can get a great look with all sorts of luscious plants. 2 of my tanks are lowtech. I can imagine I will always keep at least one, if not 2 lowtechs. And of course it's much cheaper.
High-tech for me has been a massive learning curve and I found it really difficult to balance at first, a big part being that I just don't have the money to get everything new and perfect. My budget is def more lowtech lol, If I was rich I would do a lot more of it and I'm sure it would be easier. I love the growth, variety and colour of the plants though and even though the maintenance is more extensive and rigorous I think I will always have at least 1 high-tech too. And of course the styles I said you can do in lowtech can be done in high-tech, you can p much do any style in high-tech which is great. Another downside to it is that I definitely get some more jumpers (especially shrimps) from high-tech than low, it's not common but it is downright rare in my lowtech.
Idk I'm pretty evenly balanced, I just think we should all try them all out and experiment more, I'm sure there are more discoveries and styles to find out there that I'd love to see. In both styles you can make things like really natural if you want which really is my goal so I'm happy either way.
