Living in Chicago I am well familiar with both chasidish kollelim.
Both are extremely chasuv places with excellent yungeleit, very pleasant and geshmak.
The Veitzener Kollel is more the williamsburg type, led by R Heshy Unger.
They have about 10 excellent yungeleit.
They recently finished a cycle where the yungeleit were tested on all of Hilchos Shabbos by leading Rabbonim. They really knew the material VERY well.
They recently got a whole new group of yungeleit for the next group.
I think even more are slated to join.
Then there is the Chicago Chassidishe Kollel (Zidichov) which is also an excellent place with very chasuveh yungeleit. They have 12 yungeleit, Led by R Zalman Leib Eichenstein.
They are more the regular chasidish style and are a little more diverse.
Very gashmake yungeleit.
They recently finnished Hilchis Basar Bchalav and Taaruvos, and were farhered as well.
Both Kollelim are flourishing mekomos shel torah, with new families constantly joining.
Th Chicago Chassidishe Kollel has produced chashuv talmidei chachamim who are well respected in the community.
They have a yungerman who now gives a daily shiur in hilchos shabbos at yeshiva kesser yona, another one is a respected maggid shiur at the famous Telze yeshiva and is extremely well liked, another one gives the chumash b’iyun shiur for 8th grade at the veitzener cheder, another one recently moved to peterson park and is known to know hilchos shabbos niddah basar bchalav and taaruvos cold.
I am well acquainted with many of these yungeleit who are very happy and feel extremely comfortable.
Some even bought houses.
All in all I think NB10 is 100% right.
These places really give yungeleit the opprotunity to extend their full time learning years by a good 5-6 years, which even if not a long term plan does give them great value that accompanies them even when they move on.
