I find the Remington Spartans a bit less chunky than the Stoegers. I also like the walnut on the Spartan better than the brazilian hardwood on the Stoeger. I have heard the Spartans are a bit more reliable, but I cannot say from experience.
I bought a Spartan 220 last summer (the double trigger version, 20ga, 26inch barrels) and it has been a great gun for the money. It has functioned flawlessly and I really enjoy shooting it, although I do not imagine it will outlast me. (Already the top lever is a bit left of center.) But, for $300 I have never regretted that purchase.
