Twitterfeed v Dlvr.it

Both are great services. Recently, we had a close look to see really how good they are.

Twitterfeed.com

PRO

- Free plan are available.
- Unlimited number of sources and destinations for free plan.
- Update is fast and updating frequency is much more than scheduled.

CON

- No control of what really passed to Facebook.
- When original link URL are same, it will be flagged as "no new feed", and won't be able to pass to both Twitter and Facebook.
- When prefix or suffix contains shortened URL, which would be regarded as same URL, it won't be able to pass to Facebook.

Dlvr.it

PRO
- Free plan are available.
- Able to choose as Shared Link, Status or Note with Facebook. 
- Able to attach fixed thumbnail image, or let Facebook to use Open Graph image.

CON
- Only allows 5 sources and 2 destinations for free plan.
- Update is much slow than scheduled.

Conclusion:

If you want a better control, use dlvr.it, especially for Facebook. If you have too many RSS sources, or want a fast update, use Twitterfeed. Overall, dlvr.it is much better.
