Enhanced Interior Gateway Routing Protocol (EIGRP) like Interior Gateway Routing Protocol (IGRP) is a Cisco proprietary protocol which is considered a hybrid type.
What this means is that it takes attributes from both distance-vector and link-state routing protocol types. If all of your equipment is and will continue to be Cisco then EIGRP is a good option, if your network is not exclusively Cisco then a protocol like OSPF is better as it is a standard and is supported by other vendor’s equipment.
EIGRP (and IGRP) is different from OSPF in that it utilizes an autonomous system number which must match between all neighboring routers for routing information to be exchanged.
