I think I have more 50s than any other lens. I just love the focal length and I have been seduced many times by the notion that a special, special lens will make my photography special. Spoiler: it won't. But don't let that stop you. Find a lens you enjoy using, learn its quirks and limitations (they all have their own) and then make your art!
Here are some boring photographs that show some of the differences between some of my 50's.
Here's the scene:

Center crop with a Summitar, wide open:

Center crop with a Summicron IV, wide open:

With a Summilux Asph, wide open:

Wiith a Heliar/3.5 wide open:

And here is the page if you want to see these boring photos side by side:

As you can see, the Summicron is nicely balanced for flare control, sharpness, color rendition, etc. The Summilux Asph is "better", but also twice the cost. The Opton is "worse" but probably could use a good cleaning. I think the Heliar wide open is as sharp as the Summilux, but its smaller maximum aperture probably masks some faults and its slow speed means that it is not apples-to-apples anyway.
So having said all this let me give you my advice: buy the Summicron. It is an itch you need to scratch. Forget about "worth it" as a criterion. No one here can answer that for you. Until you try this legendary lens you will not be satisfied that you have walked the walk. If you don't like it, resell it. I very much like mine. But I own both a modern Sonnar and a Planar and switch between them when the mood takes me.
BTW, my favorite? A 45/2 Planar for a Contax G which I had converted to M mount. Man that thing can render a teacup like nobody's business. But the very listing of it as a choice should tell you I am nuts. Buy the Summicron. Love the Summicron. Leave the Summicron.
By the way, you will notice in the general link above that even the Opton performs pretty well stopped down to f:4 . . . just sayin.
