I just finished all of 5 CCVP exams plus IPCCX within 10 months (all with 945+ scores). Achieved CCNP years ago (only 2 exams with 900+ score, pass routing at 2nd try).
CCVP vs. CCNP
Personally, I think CCVP is far easier than CCNP. CCNP should get more value than CCVP in longer run.
CCNP focus more on fundamental and turely be networking so needs to be very detail-oriented. Easier to step into networking field, but to be well skilled need much longer time and more self-learing and excercise.
For instance, regarding OSPF, I have deployed/designed three different rollout before and still need to read documents to cover my latest design to bridge two dis-continued backbone via virtual-link. For spanning-tree, I saw two many cases in real world people don't even realize its existence in LAN, not to mention how to tune and stablize it.
CCVP is more on application level. It may be slightly difficult to get started (or understood) but be more easy to climb up since it is application level and similar to MS stuffs.
My thoughts above - to judge my thought here is myself: IT guy with experince - 14yrs+ networking, 3.5 yrs voice and 12yrs+ Unix.
Any more thoughts, Gang?
