Oops I meant which is *less* likely to break/leak, if you are looking for deciding factors, or an interesting project. From the sims I’ve seen it seems like the bottom center seam on the long panels gets a lot of stress.Neither would break or leak if made properly and supported with a good stand. I am leaning towards a custom crystal dynamics tank like the last one I have. The euro brace and reinforced seams have held up really well.
