Like Snappyllama, I love all my children.
Having said that, though, if I had to choose only one mold to take with me to a desert isle, my absolute #1 choice to take with me would be my first ever 'real' mold, which was given to me as a gift by my sis who was one of the first testers my soap. I suppose that gifting me with a mold was a hopeful sign that she really like my soap!
Anyway, the mold was handmade out of wood by a former member here (does anyone remember TOG molds?), and as troublesome as his latter-made molds proved to be according to the testimonials I read, mine was an early-made mold and has never given me a problem in all the 9 years that I've had it- and I still use it a lot.
The mold is a completely collapsible, very clever combination log and slab mold that holds 4 lbs. of soap total.
I can either make a single 2-pound loaf with it, or two 2-pound loaves side by side at the same time, or I can use it as a slab mold. Filled part-way, the slab will make 9 bars of the thickness of my choice, and filled all the way up to the top, it will make 18 bars @ 1.25" thickness. Also- I have not done this yet, but I suppose it can also make 1 or 2 sample 1-lb batches if I pour only part-way into the loaf compartments (they should each make 4 slab-style bars).
It came with Funky-Foam liners, which I've long since discarded for better lining material- i.e., heat-resistant mylar, and also silicone fondant mats and/or bubble-wrap.
Anyway, I love the versatility of this mold, and also the ease of unmolding no matter which different lining option I might choose to use with it at any given time, all because of the mold's complete collapsibility.
I also have a back-up mold of this exact type, but it is slightly taller in height to make fatter/thicker slab bars if filled all the way to the top. I bought it from Dianna's Sugar Plum Sundries. It may or not be TOG-made, I don't know since it doesn't have his mark on it, but it works just as great as the other one.
My other well-loved 'babies' are:
-my Woodfield's collapsible tall and skinny wood log mold with silicone liner
-my Brambleberry collapsible wooden vertical mold with removable divider. I don't like the acrylic liners it came with, but it thankfully takes very nicely to other lining materials such as silicone fondant liners, mylar, and bubble-wrap
-my 1 lb. wooden collapsible tester mold made by TOG
-my Brambleberry PVC tube mold with its awesome (included) liner
-my 2 ED silicone molds with swirling inserts, even in spite of the pesky bubbling problem they give me. The different swirling possibilities that the inserts give me, and also the different cutting choices that the dimensions of the mold give me, make all the planing that I have to do afterwards worthwhile.
-I also love my Milkyway-type molds for pouring off any excess batter, and also using them for squishing my soap scraps into in order to make decorative bars out of them.
