Default 2.1 stroker or 2.5l swap?

So I just leaned out my ej20 engine because I didn't get a tune. Big mistake on my part and now I'm paying for it. I'm looking for a new oem2.5l engine or rebuild mine into a 2.1l stroker.

The car is a 2002 wrx vr39turbo, full exhuast, and intake, with 199k miles. And soon to be 820cc injectors and tune.

My question is what would be average estimated total cost be on these two builds? and what's your opinion on the Stroker?
I'm a moderate driver too. I only go fast if im late to work. other then that I just cruise

I have an 02 that I just had rebuilt. I am still in the break in phase so I cannot comment on the 2.5 swap other than I was in the same shoes you are in now. I also hemmed and hawed for a couple months before I decided to go with the stroker. I will give you a list of other mods I added so you can judge if this is the way to go for you:

Manley 2.1 Stroker kit
Nitrided Crank (I dont think these are readily available anymore)
ID 1000 injectors
AP Fuel rail kit with lines and regulator
Aeromotive fuel pump
AP equal length header
STI oil pan nad dipstick
Blouch 16gxt turbo 8cm
ACL Bearings
Killer Bee Oil pickup and windage tray
STI Oil Pump
Cleaned up heads (buckets, new guides, minor resurfacing etc)
90k parts
Moroso Catch Can
AP lightweight pulley
Koyo Radiator
All new Samco Hoses
FMS TMIC
Im sure theres a few more I forgot.

The car already had a couple light mods, Invidia Turboback, Grimspeed BCS, AEM Intake

My cost from the shop was around 6k which included all the labor (except the fuel system), stroker kit, internal parts, machine shop time ( they did the internals, cleanup and B&B). They also let me purchase all the upgrades and they did the labor for free since they had to re-assemble anyway.

My parts cost was about another $3500 which included all the other performance parts, turbo, headers, Injectors, fuel pump, fuel rails and lines, catch can, pulley, radiator

The shop I used was 6 Star out of Schaumburg. They were superb to deal with, very up front and honest. They had some issues getting to the finish line, but they didnt beat around the bush and let me know what was going on. If you go this route, picking your shop will be the absolute most important thing you do. I understand there may be limited choices in your area, but if you dont feel confident in the builder, just dont do the build, plain and simple. On the other hand if you plan on doing this yourself......good luck. Hope this helps!!

Thanks I appreciate the feedback! I'm having a hard time finding a rebuilder who wants to do a 2.1l stroker in my town so looks like I might just go with the 2.5l with cp piston heads.

I'm running this and have no engine issues after a year and a half and three Austin/Albuquerque trips. Motor has stock 2.0 heads with STI matched combustion chambers and stock STI head gaskets. I personally think these builds are very similar and mostly depend on whether you want a built motor or not. Depending on your goals, I would even consider a 2.5 SB w/o the forged pistons (you can get one shipped from Import Image for ~1900). You can reuse all your old 2.0 parts and either cap or T-in the breather in the 2.5 block. Just make sure to get the 2.0 gasket kit with just 2.5 head gaskets since the 2.0 and 2.5 cam seals and valve cover gaskets are different (those are the ones I can think of off the top of my head).
