Peps is better
I´ve worked with both CAMs, I get surprised when G-Auto says PEPS cheaper than ESPRIT, sure?, i don´t think so, here in Europe at least is more expensive than ESPRIT, anyway it is also a far better CAM.
ESPRIT has a really helpfull tools, multicavities, solids...., but they have still too many bugs, sometime it takes too long to make some easy programs, on the other hand, the tools to edit, draw, and give technology are really simply and easy to learn, but for me the worse thing is the postprocesor, when cutting 4axis programs it makes too long programs with many lines, the result in your piece could be some marks.
PEPS´s editing tools are really complex, "too german" in my opinion, i mean, to edit really simple things you must do a lot of operations, but it has many many diferent tools to give the technology to your pieces, really easy to use them and really fast, and many different option for your: glues, skims, pocketing cuts....they have also a really good solution for a rotary axis, and the best, the postprocesor is really good, for pocketing, 4 axis etc..
My experience was cutting one 4 axis piece, with ESPRIT´s postprocesor it took more tha 200 lines, the result was a stepped piece, the final result was many lines in the final surface, when people from PEPS postprocesate my program, they made it is less than 20 lines!! the final result was no surface lines.
If I had to choose one of them i would be depending my technologic requirements, if i do normal work, no complex things(pocketing, 4 axis, rotary axis, form tools, ...)y will choose ESPRIT becouse the relathionship quality-price is really good, but for complex things with no doubt i will choose PEPS! even if i have to pay more.
