No, we do not disagree, in terms of NAS storage. I think the Synology is a better Raid technology and at least with the older Drobo models I am familiar with you get more horsepower for the dollar although a "decent" Synology NAS would probably cost a couple hundred more than a Drobo FS - but I think money well spent.
The Synology also has far, far better built in software. Drobo relied on user developed apps that for the most part never got written, and has some other basic shortcomings you won't find with a Synology NAS.
For direct access storage (DAS), I have not found what I consider to be a better and generally acceptable solution. This post was initiated in response to problems with a Drobo DAS unit so that has been the thrust of my discussion, and I went into the detail I did because I know that the Drobo is a very misunderstood product.
There are good reasons to choose something other than a Drobo but I rarely see an unbiased and knowledgeable discussion of those somewhat complex issues.
