The Eagles DC job isn't that attractive. A lot of older players on that defense so I am not sure I'd ever consider the two opportunties close to equal, despite the Eagles high sack total. Its not something thats going to be sustained, even past this year. This group is going to break up but on paper its an impressive collection of DL, especially at DT.
James Bradberry and Chaucey Gardner-Johnson are both free agents. Fletcher Cox is old. Howie Roseman is generally one of the worst drafters in the league although he has found a solid recipe for signing veterans to 1 and 2 year deals and getting a lot out of them.
It does appear the Eagles are likely going to use the 10th pick in the draft on a defensive player, probably a DE or CB.
Phillips, Wilkins and Chubb are much more attractive long term, for a DC to work with than what Philly has. Aside from the part where you actually have to show up to South Philadelphia everyday for work......BRUTAL.
