Q: Do you have a preference between RTX and LMT?

Q: Hi guys, thanks for the excellent service. Generally TFSA is the place for high growth but my highest growth has been in my RRSP. Is there any compelling reason I should sell anything in RRSP and rebuy in TFSA (e.g., NVDA)? I realize I will be taxed on RRSP withdrawals while TFSA withdrawals are tax-free - but - my RRSP has a lot more cash than my TFSA so there isn't room to move all my growthy stuff over. Because of the relative size of RRSP to TFSA, if I were to do equal weighting of all stocks, I'd only have 4 different stocks in my TFSA, which perhaps is fine? Are there any obvious adjustments that you would make to the following:

RRSP:
XQQ 13.68%
VXC 12.03%
NVDA 7.64%
AAPL 6.70%
JPM 4.73%
BNS 4.52%
GOOG 4.32%
ENB 4.13%
MSFT 3.98%
AMZN 3.86%
RTX 3.51%
COST 3.42%
PG 3.11%
DIS 2.82%
CASH 1.32%

TFSA:
GSY 5.28%
CRWD 3.31%
VEEV 2.50%
ROKU 2.44%
SHOP 2.26%
WELL 0.85%
XBC 1.08%

RESP:
LSPD 0.79%
BYD 0.76%

NON-REG:
SLF 0.51%
T 0.42%

thanks,
