Here are afew different swingarm skidplates that I have used in the past and present. A couple that I made (they are the easy to identify) and some that were produced by way bigger companies.
All of them were used (except for one) for racing off road.

Left: stock '86 trx250r
Right: homemade for '86 trx250r

Here is a homemade skidplate for '88-9 trx250r no-link. Its 1/2" thick bottom and 1/2" gussets welded to the swingarm to mount up the skidder.

Here is a Roll Design Lobo II aluminum skidplate I got off of ebay, that I straightened and added gussets to help strengthen it up. The badger skidder wasn't available to me at the time so I found this one to use in stead.

great pics.

which ones worked best? How did the chrome moly hold up vs. alum.?

Also, do you not run any sort of chain guide to prevent derailing?

thanks

To answer the first ? , I never ran them at the same time but I have to say that the heat treated ones held up the longest. The abrasion resistance ( the ability to not get deeply scraped) made them not lose material and become less effective. Plus they would not bend hardly at all. Heat treated chrome moly is the best. Next would be heat treated aluminum, then untreated aluminum.
If you can have them heat treated you will appreciate the life expectancy.
Never ran a chain guide of any kind on the long travel swingarms, just took extra time to make sure to adjust the chain correctly. Which was slightly slacked w/ rider on board. Counter shaft ,swingarm pivot bolt, axle all in the same plane. Always keep an eye out for too much slack, and your left center cases will stay alive. Plus keep your chain fresh, always use a good oring chain.
