What’s the difference between them?

Performance

Both have DeWalt’s 15-amp, 3,800 rpm motor, so they both deliver the same basic performance. It’s a good, powerful motor that if you use a nice sharp blade will cut through most wood like a warm knife through butter. Both delivered good long, deep precision right out of the box without the need for much upfront calibration. Although performance will always be everyone’s first question, in this case you can go right to the question of price versus versatility.

Price

If price is the driving consideration in your choice between these two, you’re going to buy the DWS709. It averages out to two-thirds the price tag of the DWS780. Considering that the DWS709 is a couple hundred bucks cheaper, that could be a pretty big incentive to forego the versatility that is the reason for the DWS780’s heftier price. In fact, since they use the same motor, we prefer to think of the DWS709 as the default saw, with your primary choice as whether you want to pay to upgrade it.

Versatility

For professionals or experienced DIYers who require precision, the general versatility of the DWS780 makes spending the money a pretty easy choice. It can deliver better bevel cuts at deeper angles. Pros will also like the laser, which is often just a pricey gadget but in the case of the DWS780 has real utility. Users who just want to make simple around-the-house things, have extra to spend on durability and basic precision will find the DWS709 everything they could want in a miter saw.

Design

General user impressions

The great thing about the Internet is that you have access to a wide range of user opinions. You don’t have to just take our word for it. We compared our experiences with these two saws with other people who used them. Here’s a quick rundown of what people had to say.

In general, people are happy with these two saws viewed through the same general conclusions we reached. Neither excelled in power, which makes sense because they have the same motor. The DWS709 is a great all-around saw that delivers DeWalt quality at a DeWalt price. The DWS780 is a better saw, mostly because of the XPS precision guidance system, but if you don’t want that you can save yourself a nifty little pile of cash. Both saws are good, dependable and powerful.

Other users find that the DWS780 also works angled cuts a little better, especially when paired with the XPS system. But, the DWS709 is still a great saw, and some users found the laser a bit distracting. In fact, the general consensus for users is that the DWS709 is probably enough saw for the average user, with the XPS something that would be attractive to people with specialty needs in a compound miter saw.

A word of caution, however. DeWalt miter saws the last few years have had a reputation of coming with sometimes faulty fences. If you buy one, you will want to immediately check it to make sure that it’s straight and true. If it isn’t, address it promptly so that there’s no risk of a bad customer service experience.

Conclusion

A lot of times, these choices are a matter of one product just being superior to the other. In this case, however, the two are from the same manufacturer and use the same motor, and both do an excellent job at miter and bevel cuts. So the question comes down to price and versatility. If you want something simple and straightforward, the DWS709 is a better choice because it’s less expensive. If your current and/or anticipated needs dictate that you need a miter saw with greater adaptability, you should spend the extra money for the DWS780. It gets no more complicated than that, and for people shopping for miter saws that’s probably a happy thing to hear.
