I currently own both the KZ Castor Bass Edition and TANGZU Wan’er S.G. 2 5th Anniversary edition, but I only want to keep one and sell the other.

I'm looking for opinions mainly based on technical performance and hardware, rather than personal preference.

Which one would you consider better in terms of:

Technicalities (detail retrieval, resolution, imaging, separation, layering)

Driver performance

Tuning quality

Tonal balance

Bass/mid/treble quality

Distortion/control

Overall technical capability

Build quality and long-term reliability

I previously owned the KZ EDX Pro and liked its tuning. I also find the Castor more impressive at first listen, but I'm trying to avoid making the decision purely based on initial "wow" factor.

If you had to keep only one of these two, which would you choose and why?

Thanks.

About a year ago I became concerned that I might have scapular winging because one shoulder blade looked slightly different from the other and my shoulders seemed rounded. During push-ups I also noticed my right arm would move slightly farther forward than my left, making things feel unbalanced.

I saw a physiotherapy clinic at that time. The assistant assessed me and said I had minor winging and rounded shoulders, likely related to desk-job posture. I was given corrective exercises and some supplements, but I didn't continue treatment or do the exercises consistently.

Recently I joined a gym and bought a 6-month membership. While doing lateral raises, I noticed that I can feel my left lateral delt working and burning much more than my right. The right side doesn't seem to activate the same way. Around the same time I noticed that my scapulae look uneven in photos, which made me revisit the winging concern.

I went back to the same clinic, but this time I was assessed by the physiotherapist himself. He checked my shoulder strength and said he did not see obvious winging. He mentioned that sometimes winging can become more noticeable when muscles fatigue, but my strength tests were normal.

He gave me a few exercises and discussed long-lever shoulder exercises. When I told him I train by myself and learn from YouTube rather than using a personal trainer, he seemed concerned that I might be performing exercises incorrectly. He suggested freezing my gym membership for about a month and returning for follow-up.

What I'm trying to figure out:

Does this sound more like true scapular winging, scapular dyskinesis, or just normal asymmetry?

Has anyone had one lateral delt feel significantly less active than the other due to scapular mechanics or technique issues?

Is it reasonable to stop gym training completely for a month when strength is normal and there is no major pain?

For those who have dealt with scapular control issues, what exercises or corrections helped most?

I have photos and a wall push-up video if that would help.

Do i have winging ? Or it's just muscle imbalance?
