That said, the Edison is fabulous, truly fabulous! ... and that can not be over-stated. I own two Edisons and I own a plethora of RPi. The edison is small and finiky... its not forgiving, and while it does have a good community it does not have the longevity nor experience of the RPi community. If you have done nothing with either start with the Raspberry PI.
The edison works off of 1.8 volts. Many folks find the RPi voltage constraint of 3v3 a PITA... edison makes that magnitudes of order more difficult. The edison is pricey, um, expensive. It needs to have a breakout board (you have several to chose from) but aside from the Galileo board none of them are easy as, well, PI. Galileo is expensive too... you can buy them together (recommended). There are also entire breakout kits from Sparkfun (must have, in my opinion)--- everything from ADC/DAC to battery (Iot kits) to breadboard breakouts, &c. You can do more with the Edison (this is just a factual statement not meant to antagonize) than you can with Raspberry PI; however, you MUST be more of an engineer to do them! Edison is meant to be an embedded computer (full gnu+linux) whereas the Raspberry PI is intended for the educational market of ideas and particularly with kids. There obviously is overlap.
Making your own boards is easier with the Raspberry PI compute module. You can make your own boards with the Edison too... but hooly cow... the connector requires a microscope to even see it! The entire edison is no larger than a postage stamp (without breakout board), so it can be embedded easily in any thing from a calculator to a cap visor.
The edison is two core; the PI is four core. The edison is an Intel processor; and unlike the Raspberry PI is entirely open source (hardware and software). That gives the Edison an advantage for the maker community... but again, you need to be an engineer to use it... its not designed for kids, and its not a toy; and, it can be destroyed instantly just by looking at it!

edit: The Intel Edison has an on-board Quark MCU. When I purchased mine the MCU firmware was not ready, so, ironically the mcu on neither of my edisons works... I'm thinking its about time to get them updated; although, Yocto works in both of them... so, I might just let them run.
Its not an either or. I have both, I love both, and I use each for a completely different purpose. I must say, my edisons have been running for more than a year... one 376 days, the other 384 days... they run cool, and they are solid as the rock of Gibraltar!
