I'm in California and we're having a pretty serious water shortage (or so they tell us) so I've been sticking to HE machines for laundry. I have 3 FL's and 1 TL washer connected I use regularly.
The Players: 2009 KM Elite, 2005 LG, 2001 MT Neptune and a 2004 WP Calypso. (I also have a 1997 small door Frigidaire Gallery FL in the house, but only run a load in it every 2 months or so)
The Sheets: 2 King size cotton sheets, 500 thread count with 5 king size pillow cases.
The Results: In the KM Elite FL (blue), it does OK maybe 40% of the time. The rest of the time I'll have to stop it, untie/untangle the sopping wet mess and re-start. If I don't, it will dink around for 20 minutes trying to distribute and spin.
In the LG, this one has never, NEVER tangled/balled up/made a rope of anything, sheets included! There are other things I really don't like about how this machine works, but tangling sheets is not one of them!
In the Maytag Neptune: Never a problem with tangling or balling up anything.
In the Calypso: I no longer wash sheets in the Calypso. Every time I have, each sheet has been twisted into a rope by the end of the cycle.
The dryers (2 Maytags and a WP Cabrio): If I'm drying a mixed load of sheets (thick/heavy & lite/thin: i.e. dog bedding) they will ball up and the heavy one in the center won't be dry. When drying the bed sheets and pillow cases, I've learned if I throw in the 5 pillow cases first, then "fluff" each sheet before tossing it in, the pillow cases won't be balled up in a sheet (and not dry) when the cycle finishes.
