What (WW2 land) rules to follow?

Despite some twenty years of 'punctuated intensity' in the wargames hobby, dominated but not exclusive to the twentieth century (and again in particularly WW2) I have yet to find my ideal set of wargame rules.The concept of "set" can be expanded to include, scale of the models (20mm, 15mm, 1/300, 10mm, 1/200 etc.), the tactical/operational level of engagement the game would represent, the timescale of turn and the simulation versus game mechanics employed.

Yes I have lots of sets (in the purchased sense), but many have not made it to actions on the table-top. Those that keep coming to mind are defined as the "good", the "hopefull" and the "sinfull". All my own personal views of course, and in no way a criticism to those who enjoy a different way/taste to mine in the hobby.

Some "good experiences" of the ones played so far have been:

• Spearhead (and modified versions thereof, played with 1/300 or 1/200 kit, a fairly large sized battle of three to four battalions a side can be concluded in a club-night)
  
• The Command Decision Series (to be accurate mainly WW2 Command Decision Version 2 but Version 3 is in my possession and has been read, played originally with my 20mm kit although I am planning another go with this set using my 1/200 kit, provides a battalion/regiment intense slog-it-out feel to a night)
• Hell by Daylight (participated in various excellent 20mm Skirmish level games, always fun and leaving a feeling of authenticity in the mouth)
• Squad Leader transferred to tabletop (can work well, but mainly with those who have already played it as a board-game, it can frustrate gamers not familiar with it and the infamous Stalingrad scenarios, again with 20mm kit)

Those "hopeful" sets yet to be tasted/tested in the heat of a club battle:

• Battlefront (of which I have high hopes to use 20mm as well as my 1/200 kit)
  
• (Canadian) Great Battles of World War Two (which looks to have some great concepts, probably using 1/200 kit)
  
• Crossfire (which again looks to have good concepts and works for a good many people, a good 20mm prospect, particularly inspired by these chaps Tim Marschall and Lloydian)
  
• Megablitz (well a few 20mm tanks should stretch a fair way in the OoB here, a very high level way to run a battle. Not a case of where are my squads but what are my battalions doing?)

Those "hopeful" sets yet even to be purchased:

• Nuts! (skirmish)
• I Ain't Been Shot Mum! (Company)
• Flames of War (although very popular something tells me I shouldn't hold my breath on this one as I keep seeing it mentioned in the "points" competition sense, though their production quality seems excellent, so popular in 15mm, but a maybe for 20mm)

Ones that suited me not, as in they have "sinned" IMHO, or failed the 'wargaming environments' in which they were played in or perhaps personalities/style involved:

• Rapid Fire First Edition (which had a notorious nights of wanton death that sealed its doom at several clubs I have attended, artillery being a notorious talking point)

Nevertheless the search continues for that "perfect" set. Visual appeal is very important for me, hence my drift away from Command Decision 2 in 20mm as the models in some cases seemed almost touching (in extreme cases, platoons of tanks almost in hand to hand combat) and it didn't carry the realistic visual feel across to me.

However my recent 20mm painting may make me reconsider this due to its modelling appeal. :)
