This has been discussed as a part of many of the ever-expanding collection of Southside Metrolink threads here, but I was hoping to focus this one specifically on the merits/shortcomings of the De Soto line as a preferred Southside Metrolink route.
I know that the East-West Gateway ultimately decided on the Chouteau-Jefferson-I55 route as their locally-preferred alternative, but my mind always inevitably returns to the De Soto route. For more of my personal thoughts on the matter, I made a post awhile back on YASTLBlog. It's also worth mentioning that Union Pacific still occasionally uses this right-of-way as does, so say commenters, Amtrak. For it to work, I'm imagining a scenario where Union Pacific would vacate the line for a long-term lease to STL/Metro. Perhaps with some land swaps to expand its Lesperance line a bit?

This is a "Cadillac Plan" map that shows full southside transit realization. The De Soto route is in yellow. Oh, to dream!
So what's your preference? Obviously, when we're able to do both lines, we will know this City has truly and finally righted itself, but for a first-effort (which, I'd think, is the most important phase in building support and altering transportation habits), where do you land?
Each route, obviously has its negatives and positives. A Jefferson route, for instance, has a more direct downtown connection, hits the edges of some of the stronger near south neighborhoods and could act as a stabilizing force for n'hoods as you move further south to Broadway/55. De Soto, meanwhile, tags some of the more densely-populated southside areas and represents strong TOD opportunity around former rail-reliant parcels. One exists at the center of east-west bus routes while the other has transfer points nearer those routes eastern termini. Both have the opportunity to stitch neighboring communities together. One would require extensive reconfiguration of surface-level traffic, whereas the other has an existing grade-separated (at most points) ROW, likely reducing the need for demo/construction.
Another option I've considered for the De Soto route is if, rather than following the ROW hump to the edge of SW Gardens/The Hill, if there was a (very expensive) dig down for a subway at Morganford, through TGP, under Tower Grove Avenue and then northward at street level (?) straight through The Grove, CWE and onward -- making it a true N-S line, rather than getting to FPSE and pitching back east toward downtown via the current Red-Blue Metrolink line (or Chouteau). Obviously, cost-prohibitive and entirely different beast than just following an existing ROW though...
