Ne2 or Ngf3 in the tarrasch French?

Guys which one is better for the intermediate player like me? So the line goes 1.e4 e6 2.d4 d5 3.nd2 nf6 4. e5 nfd7 5.bd3 c5 6.c3 nc6, now should I go with ne2 or ngf3? I been experimenting with ngf3 and the pawn sac line but never really got much success, so in my recent games I went with 5.ngf3 c5 6.c3 nc6 7. be2 qb6 8. nb3. Then I learned that I can just save the hustle and just go 5. bd3 c5 6.c3 nc6 7.ne2 and my pawn is very safe. So should I switch the lines up or keep experimenting and learning the theory of ngf3? 

wait

your pawn is "very safe" in Ne2 lines but not Nf3 lines?

how is it any different?

@Ilampozhil25 after 7.ne2 qb6 you can go 8.nf3 and the pawn is guarded , but in the ngf3 line you are basically obligated to just sac it with 8.O-O cxd4 9. cxd4 nxd4 10.nxd4 qxd4 11. nf3. You can't go something like 8. nb3 to guard the pawn because ... c4 just forks the 2 pieces.
