I've personally used the iCE40 and iCE5LP in my larger designs, wonderfully
capable and affordable devices.

I still have a few 84 pin PLCC XC95108 5V CPLDs Originally, I did a
tape controller design with one before Xilinx discontinued them. I
figured that using a discontinued part was not the way forward, so I
dropped the project. Xilinx did/does have its ISE design suite, which
is fairly easy to use.
Eventually, it turned out that using a reasonably fast MCU with 5V
tolerant I/O worked just as well and avoided the "mystery in a chip" of
a CPLD.
