To each their own, for me I will always prefer ALD-52 to L25. ALD will always have less anxiety, vasoconstriction and manic thought patterns, that alone takes the cake every single time. Let alone the other benefits, less toxic and easier sleep as well. The potency and seriousness is still there for me, in fact a deeper more introspective headspace, and more controllable trip in general. What makes LSD crazy is it's manic nature and chaotic headspace body load and visuals, there's truth hidden behind all that and it's just easier to see on ALD.
Yes it's very subjective as "seriousness" to you is the manic, chaotic fast paced nature. I would prefer to have more control and foresight allowing free willed travel through hyperspace.
