Last year at Compton's, I shot both bows back-to-back, and was impressed with both. I had already shot the PCH many times on other occasions, but it was my first time shooting any of BigJim's bows. The TC was beautiful, impressive to shoot, and looked very clean and well-made.
They are, indeed, two very different types of bow. The 58" TC did not stack when I got it to full draw, but the 58" PCH did. (I draw about 31"). For comparison, the 58" Black Widow PSR did not stack at my draw. But I'd have to go 60" with the PCH.
The TC was whisper-quiet, and felt stable enough to me, even though I prefer longer bows and more mass weight in the riser. If I were going to get either a PCH or a TC, I'd buy... a PSR!!! I prefer the grip of the BW longbow/PSR. Of the three, I prefer the PSR, then the PCH, then the TC. But remember... I'm no expert, just some guy typing at a computer... and opinions vary widely.
If at all possible, try before you buy.
