I'd say OEM (AC Delco) or Walbro only. Walbro has a reputation for performance, quality, and reliability.
IN A NUTSHELL:
"When will my fuel pump crap out?" can be best answered by:
"When your fuel pressure doesn't meet spec".

I did mine at 139,000.... The pressure was good at idle, 42 PSI..... But then I could bring up the revs it would go to 45Psi and then drop steady... Once it dropped to 30-32 I knew the Pump was facing death.... As I no longer had any trust left in the pump( Don Had to take a 2000 miles round trip and didn't want to be left stranded by an unhappy pump ) I decided to replace the pump using an OEM AC Delco pump.... After the replacement the Fuel pressure was easily 50 psi with the ignition on, At idle it was 43-45, bring the revs up and the pressure would go up, dissconnect the regulator and poof 52-53 Psi with no drop... This was a big diffrene as compared to the older pump, it just couldn't keep up with demand.... Car seems to start easy every morning too, Barely touch the key....

Don and Bill...I followed the same logic without consulting anyone! 
That'* exactly what I thought when I replaced my pump...pressure was low, sluggish acceleration, and took longer to start.

Funny thing on my 93, If I started it within a second or two of ignition on, it was fine, but 4 seconds after ignition on or later, it wouldn't be happy. It came up ok, but bled down too fast.
The 95 doesn't have that problem, it'* just a slow-starter each time, regardless of delay. It'* fuel pressure isn't quite as bad as the 93 was, but it'* close.
Maybe I can limp it until July and get some help dropping the tank at WCBF06.

If its holding pressure as opposed to a steady drop then you'll be ok for a while...
Oh on a side note for everyone..... My old pump could be heard inside the car with the windows up stereo turned down..... I could hear it whining/Groaning, Had to have the music on to a certain degree to drown it out.... The new pump is very quiet, I really have to pay attention in the morning to hear it purrr

Mortehl'* pump was so bad that it would start to lose ground at anything over 1,500rpms. My fuel pressure gauge has a 7 foot hose, allowing FP to be monitored under actual driving conditions.
Sitting still and whacking the throttle is one ithing..but actual driving really shows any issues.

Transmission jack...you can take advantage of the 12"x12" (or bigger) flat plane. No need for plywood. Get full circular movements on the casters. You get 100% pivot out of the plane. And, it'* more sensitve to slight increases and decreases in height and plane adjustment. I also liked it because the pivot adjustment allowed for me to accomodate the car being on jack stands on an angle. My jack (or second hand) could accomodate it nicely!
